Java and Python are two of the most popular and influential programming languages of the present time. Beginner programmers often get confused, one of the most frequently asked questions is should I learn Java or Python? Is Python is an excellent programming language to start with? Which programming language would you recommend for beginners to learn first etc.? Since I am a Java developer, my opinion is biased, I will always suggest you start with Java and then learn Python, but if you ask this question to a Python developer, you might get just the opposite answer. I have well documented my reasons as to Why Java is the best Programming language and Why a programmer should learn Java. One of the most important reasons you would see in that blog post is an active Java community, which will help you throughout your Java career.
You can ask some beginner stuff starting from how to set PATH and classpath to advanced material about debugging Java programs in Eclipse, no matter what kind of question is, there is always someone in the Java community, who is ready to answer and help you.
This is one of the reasons that StackOverflow is full of Java questions. By the way, Python is not a spring chicken anymore, it has fully grown and given stiff competition to mainstream languages like Java and C++.
When I first come across Python, I thought it's a scripting language, but that is an understatement. You can do object-oriented programming in Python as well. It's also used heavily in web development sites like Reddit are built using Python and machine learning, and data science make Python even more useful.
From a beginners point of view, I always suggest picking a language that is easier to learn, powerful to attract you, and have strong community support, now both Java and Python fits this bill, and until you do some excellent comparative analysis, you can not decide which language to learn from Java vs. Python.
Thankfully, we have an infographic, which highlights some vital differences between Python and Java, I am sure after taking a look at this Infographic, you will be able to decide which is the right programming language to start with.
If you already made up your mind to go with Java, then The Complete Java Masterclass course by Tim Buchalaka on Udemy is an excellent course to start with. It's not only the most up-to-date course and covers the latest Java features from recent releases but also the most comprehensive and well-structured course which makes learning way easy.
Before learning any programming language, it is a must to know the difference between them.
It could be wrong to declare that Java can be less productive compared to Python due to numerous elements.

Python vs. Java - Infographic
Being two different programming languages, Java and Python can be useful tools for modern developers for developing applications.Before learning any programming language, it is a must to know the difference between them.
It could be wrong to declare that Java can be less productive compared to Python due to numerous elements.
But, no matter whether you choose Java or Python, here are excellent resources to learn both Java and Python in 2024
- The Complete Java Masterclass
- The Complete Python Bootcamp: Go from zero to hero in Python
- The Python Mega Course: Build 10 Real-world Applications
You can join these Udemy courses to learn both Java and Python from scratch in 2024. Since I am a Java developer, I personally suggest you learn Java in 2024 as it is one of the most popular languages for backend development and Android app development.
Let’s go through this infographic to learn some differences:
From this Infographic, you can easily see that Java is very verbose than Python. It takes 10 lines of code to read from a file in Java, while it only takes 2 lines of code in Python. This point goes towards Python because beginner programmer definitely likes to write less code.
The second point is about the static and dynamic type of variable, In my opinion, you need a strict programming language and compiler to detect silly mistakes made by beginners, In Java, you can not store an integer value in a String variable.
So on this point, my vote goes to Java. Speed, which is a crucial thing on enterprise-level application development, you can see that Java is faster than Python, but do remember that you need to compile and run Java programs, while Python doesn't need to be compiled.
Python shell can directly interpret python commands, which means easier for programmers. So now Python and Java are both 2 and 2.
This is an important reason to learn Python for beginners because it just makes it easy to try and learn, and if you choose to learn Python, then The Complete Python Bootcamp by Jose Portilla on Udemy is an excellent place to start with. It covers Python 3 from scratch.
Things have improved with the introduction of JShell in Java 9, but I still rank Python better in terms of quickly whipping up a script and running.
You can also see that hello world in Java takes more lines than hello world in python. The rest of the examples you can analyze by yourself, but all it comes that both Java and Python are equally capable, no one is lesser than others.
As a Java developer, I can say from my personal experience that you will not regret learning Java and choose it as a career; of course, you can learn Python anytime, and it's suitable for writing small utilities, but Java is Java.

ReplyDeleteWhat about concvurrency in Python?
Concyrrencvy, the strong part od Java, one of the most important things in serious corporate programming.
Secundo
I can't understand why
public static void main(String[] args)
iż always set as prime example for code length in Java?
There is usually one main() method in project but person who doesn't know Javacould think that it is nessary to out main() method Evert time hi wants to write text to console.
Tertio
Java is owned by Oracle, then it iż obvious, that Google and other "community" do not lukę Java despite the real cobs and pros of Java and Python.
In my humblewd opinion comparing Java and Python is lukę comparing C and Perl and trying replace for ideolgy only with one to another.
Your IO comparision is seriously flawed...to read a file in JAVA one needs no longer than two lines of code as of JDK 1.7...you are writing code as one would do in 1.5...Update yourself mate
ReplyDeletePython code is not doing any automatic resource management. You woild code some thing like this:
ReplyDeletewith file('/path/to/file','r') as f:
print f.read()
This will make sure file is closed at the end of the with statement.
Java is a poor language for beginning programmers. Not because python is easier or python programs contain fewer lines of code. Java forces you to program in one way and one way only, a particular form of object oriented programming. When I tell this to people their reaction is often "But object oriented programming is obviously superior to procedural programming!" The fact that they consider the only alternative to java oop to be cobol style procedural programming it's evidence they have been stuck in the java constraints way too long.

ReplyDeleteI honestly cannot consider Python as a _programming_ language, at least a serious one. For me it is just a mess of ad hoc hacks w/o any noticeable consistency behind. In addition its libraries (well, those ones I've looked at) look like they have been created in a rush w/o any design and even taking into account common practice and standards. I do believe that it can be used for quick and dirty scripting but cannot imagine how any serious software can be created with Python. I think that it is a huge step back from Perl which has at least an elegant design. I've heard that PHP is even uglier, but can barely imagine how it can be.
ReplyDeleteI think you should inform the stupid people in Google, the are using the inferior Python.
DeleteNice Difference for python and Java
ReplyDeleteU will Provide a such a good thinks for us..
its Great stuff....!!!!
I would like to disagree about the speed too. But I would like to admit that my benchmarking has been confined to mere literal operations. for example I tried the below : [sum (2^i) where 0 <= i <= 63] and python has beaten java to dust. Surprised (and encouraged) by that, I tried other similar operations, and guess what?? Python is a clear winner.
ReplyDeleteN.B. I am a Java developer with 7.5 years of experience and had been introduced to Python only a month or two ago but I am liking Python.
also if you have some resource hungry part of your program, you can write a modul in c for it.
DeleteSo you have learnt Python using 2.x. Then comes 3.x and breaks many things. So you have to learn again. What a great language Python is!
ReplyDeleteAfter 10 years of C++, I've been doing almost exclusively python for 3 years, and I started to learn java today. On the performance side, python is actually way faster than most people think, because (i) cpu-expensive code is typically written in C (ii) objects don't get copied under the hood. Does java have introspection capabilities? That's one of the very strong advantages of python over C++.
ReplyDeletejava is java. lol
ReplyDeletehaha, java is a pretty bloated language, even if it has more features and abilities than python would have.
ReplyDeleteYou can actually read an entire text file to a String in Java in one line:
ReplyDeleteString text = new Scanner( new File("poem.txt") ).useDelimiter("\\A").next();
python is easy compare to java...I was working on java 3yrs...now I am working on python....But for a large app java is better.....
ReplyDeleteI have used Python for nearly 9 months and I don't consider it as a serious programming language for the enterprise level applications. It is a nightmare to write large nested blocks of code, since there are no block separators like { } in Python. If one wrong space character could make the whole program logic wrong. It is surprising that Python does not have arithmetic operators like ++ or --. May be the authors of this language intended for only as a scripting language!
ReplyDeleteIt has arithmetic operators like ++ :
DeleteIn python it is += ,*= ....
imo writting large nested blocks of code is a not a good practice in any language.
Deletealso, i am not sure if you took your time to really learn python, it has very different philosophy in many areas. for example using equivalent of ++ (+= 1) is very rearly needed in python compared to c or java. it is flexible so it will allow you to write program like it was java, but it is not good.
You simply don't understand (yet) the "pythonic" way.
DeleteIf you have a problem you think it should be easier in python it's because python has a better and simpler way than the other language, and you still don't know it.
Python was made with one thing in mind: readability matters.
I guarantee to you every problem has a simpler solution in python.
great difference between java and python
ReplyDeleteFirst, I'm a statistician, and the usual languages in my field are mainly SAS and R (and sometimes VBA). For many tasks related to my job, I prefer Python. I have also used Java in the past (versions 1.3 to 1.5), and tried many other languages. I use Python since around 2002.
ReplyDeleteTo answer one post, a precision : Python has += (and also -= *= ...).
Regarding speed, Python is slow, when relying on "pure" Python features. If you use mostly an underlying C routine, of course it's different. On the other hand, Java has just-in-time compilation, so should be almost as fast as C, unless you rely too much on objects and automatic boxing (but it's quite frequent).
Java is much more verbose than Python. Regarding indentation by space, it's absolutely not a problem, and certainly not worse than indenting with curly brackets. Both are difficult to read if there are too many indentation levels, but it's a problem with the program (and the programmer), not with the language. A too long routine should often be proken into smaller pieces.
Python 3 breaking compatibility with Python 2 ? Sure, but the things that really change, change much less than Java 1.3 (or even 1.5) vs newer versions of Java. It's very easy to port from one version of Python to the other (and there is even an automatic tool for most of the trouble).
Python not a "real" programming language ? What a joke. It has pros and cons, as any other one, and it has proved to be a rather good one. That Python is a good language for your task or not, depends entirely on your task.
I have used both Python and Java quite intensively, and there are a few reasons I now use almost only Python :
- much easier to type : less verbose, no need to declare variables
- Python "philosophy" : often one way to write something, or at least one "good" way, not as in Perl or Ruby for, example
- good data types (list, hash, set), list comprehensions and generators are very usueful (and very easy syntax for generators)
- no trouble with silent integer overflow, there is no integer overflow at all
- very good library for all kind of OS support, plus zillions of other libraries for any need
- speed is not a concern : as design and coding take much longer than running the program in my case (file management, statistics, reporting), I prefer a better readability and easier coding as in Python
- very easy to write modules
- regarding comparison with Java, ability to program in non-OOP style is much appreciated !
- some functionnal programing features, mainly closures
- introspection and ability to produce code at runtime (exec/eval...)
Somes reasons I think Python is not perfect either :
- lack of goto or catch/throw constrcut as in Lisp (which is not the same as exception handling), or at least labeled break/continue. It's annoying in some situations, for example when you want to exit an inner loop. There are workarounds, but I still miss Lisp for this
- syntax for classes is awkward
- lack of a good compiler (pure Python is too slow, compared to Lisp, which is also a dynamic language)
Sure, there are situations where another language would be better (C, C++, why not Java), but there are many cases where Python simply shines.
IMHO Python is good for beginners. Java's better for other cases because its usually a bit faster than Python. There is one more reason why many programmer prefer Java since it has good library support, and it's the only native way to do Android.
ReplyDeletethen what the heck was java doing till 1.5 for file io?
ReplyDeletedude .. the really power of python comes when everything is dynamic . and for static you can guess .. its kids play . the simple reason java is widely used coz it gained its popularity from sun labs . while guido von rossum was a simple student.
Python is slower than java??
ReplyDeletePython is far from perfect...
ReplyDelete>>> tup = ('tup')
>>> type(tup)
>>> tup = ('tup',)
>>> type(tup)
" In Java you can not store integer value in a String variable ".
ReplyDeleteIn Python either because Python is a strong typed dynamic language. The variables in Python are described by the value that has been assign to. The variable by itself has not any type. Try print(x) and you will get an error. So when you type:
st=100
and then
st='something'
the variable st is assign to int and then to String type.
Whenever I see lines such as:
ReplyDeletepublic static int foo() {
I cringe.
No offence to Jave, but Python is my favourite by far. And there are no huge differences between Python 2.x and 3.x syntax-wise, the biggest problem is that many important libraries have not been rewritten yet.
python is easy to learn and its fun too...
ReplyDeletePython is slower than JAVA while you don't compile it.
ReplyDeleteAny day, I will choose Java over Python because of just one reason, Java is strongly typed language. A strongly typed languge will catch all your typos at compile time which will only be spotted at runtime in caes of weakly typed language like Python. Of course, you should use proper types instead of just String to represent anything e.g. number, floating point number, employee etc. A strongly typed languge encourage you to use Types to avail full benefit of compiler, then there is enum :)
ReplyDeletehello world
ReplyDeletepython is python, lol
ReplyDeletejava is love
ReplyDeleteJava is an elegant language. And, Microsoft borrows from it in C#. Nobody is suggesting Python style is worth repeating in other languages. RDM
ReplyDeleteYou can do file reading in one line also in Java.
ReplyDeletehttp://stackoverflow.com/questions/3402735/what-is-simplest-way-to-read-a-file-into-string
Java is Java - true
ReplyDeletePython is Python - true
My vote for Java
Do not confuse dynamically typed and statically typed with weakly typed and strongly/strictly typed. Make no mistake, python is strongly typed.
ReplyDeleteJava Is Java...I have started learning Java..., I'm loving it..
ReplyDeleteJava is great and Python is great but you compare the two language to Perl then Perl sucks, ugly, and unfashionable..
ReplyDeleteThis article is old. JavaScript is number 1 in popularity now (see Stack Overflow and Github). Rightfully so, since it is much faster and more expressive than Python.
ReplyDeleteYes, Python is a horrible language to learn first. You may able to do a lot in Python with very little in time investment, but the bad habits you will learn by figuring out how to code in a dynamic language will ultimately lead you into a just so-so programmer. You are better off learning how to program in Java or C#, and then move to languages like Python, Ruby, and then on to C when you need speed.
ReplyDeleteTrust me, bad habits are hard to break and you are better off learning a strict language before you dive into the Wild West.
Python is better for system administration tasks, primarily as the bash scripting substitute. It has much more clear syntax and does not require expensive JVM startup.
ReplyDelete@Unknown, indeed, many organization uses Python for automating stuff instead of writing bash scripts.
ReplyDeleteI would like to add that Python is apt to create a sophisticated system that could be integrated with the production.
ReplyDeleteI believe programmers can be more productive with python.Besides,productivity is not a measure for programming skills.Its all about our interest and knowledge.The only aim we should focus should be to encourage more skilled young programmers to lead the future.
ReplyDeleteFor more info.: https://bit.ly/2CyIgGU
I am learning programming these days as a newbie. My only previous working knowledge and experience is in PHP (web development).
ReplyDeleteAs a newbie, Python feels like learning English language. Java makes me feel like I am learning a programming language.
Did a little research and realised that almost all important softwares (that matters) are in Java while almost all python based stuffs are childish (that doesn't matter).
As an experienced java programmer, If I get opportunity to work in python should i grab it or not ??
ReplyDeleteFunny how all the Python bashing have aged pretty fucking bad, especially calling the projects made with Python childish is something only a freshman would do.
ReplyDeleteNeither is a bad choice but for learning coding definitely start with Python. Furthermore Python have overtaken Java as the top language used within faang.
