Difference between Dependency Injection and Factory Design Pattern in Java Spring

Learning a Programming language like Java or Python is easy but writing production quality code is difficult. Coding is as much an art as much the Science behind it. In order to write good code, you need to carefully design your classes, their dependency and how to use that. This is important so that it can survive the constant change throughout his lifetime. If you have been coding for some time then you know that SOLID principles and Design Patterns help you to write better code. This is obvious because they are proven the solution of some common problems software developers face all around the world. But, knowing just the design pattern is not enough you also need to learn using the right design pattern in the right place.

Top 5 Data Structures and Algorithm Online Courses for Programmers

Both Data Structures and Algorithms are one of the most important topics for programmers. The best thing about them is that they never get out-of-date and any investment you made in terms of time and money will pay rich dividends for a long time. I have also found that people good at algorithms and data structures are often a better programmer than others. They tend to improve your programming skill and coding sense and that's the main reason I suggest all kinds of programmers, from junior to senior to spend some time revising, refreshing and honing your data structure and algorithm skills. Most of us first heard about them in school and colleges but didn't understand at that time. At least I can say that for me. I first heard about array and linked list on my engineering college.

10 Object Oriented Design Principles Java Programmer Should Learn in 2019

The Object-Oriented Design Principles are the core of OOP programming, but I have seen most of the Java programmers chasing design patterns like Singleton pattern, Decorator pattern, or Observer pattern, and not putting enough attention on learning Object-oriented analysis and design. It's important to learn the basics of Object-oriented programming like Abstraction, Encapsulation, Polymorphism, and Inheritance. But, at the same time, it's equally important to know object-oriented design principles. They will help you to create a clean and modular design, which would be easy to test, debug, and maintain in future.

Gone are the days when software is developed by a small team of onshore people.

Difference between application/x-www-form-urlencoded and multipart/form-data in HTTP/HTML?

Recently in one of the Java web developer interview, one of my readers asked about the difference between x-www-form-url-encoded and multipart/form-data MIME types. In HTTP, there are two ways to send the HTML form data to the server either by using ContentType application/x-www-form-urlencoded or by using multipart/form-data. Even though both can be used to send both text and binary data to the server there is a subtle difference between them. In the case of x-www-form-urlencoded, the whole form data is sent as a long query string.

3 Best Practices Java Developers can Learn From Spring Framework

There is no doubt that Spring Framework is one of the most popular Java frameworks and makes it really easy to create real-world, enterprise-grade Java applications easy by providing features like dependency injection and inversion of control. But, to be honest, Spring is much more than just another DI and IOC framework. It goes one more level to simplify many of Java APIs e.g. JDBC, JMS, Java Mail etc by providing a useful layer of abstraction. It's much more easy to work with JDBC with Spring's JdbcTempalte and other utility class. They remove most of the friction Java developer faces with respect to executing SQL statement and processing ResultSet to get the Java object they want.

Top 5 Programming Languages Programmer Should Learn in 2019

I have read somewhere that programmer should learn a new programming language every year ( I think it's code complete, not sure, though), but if you cannot do so, I suggest to at least learn following five programming languages to do well in your career. Everybody loves polyglot programmer and an all-rounder who is versatile enough to write a quick script and can also write complex Java programs. In fact, it's almost mandatory for a senior developer to learn more than one language. Interviewers are giving more attention to an engineer who has good experience with multiple languages e.g. C++ and Java goes quite well, so is Python and Java. I personally like Software Engineers who have strong experience in either C++ or Java and can write scripts in groovy, Perl or Python.

How to Remove a key value pair or Entry from HashMap in Java 8

In the last article, I have shown how to remove key/value pairs from a map in Java based upon some conditions like remove all entries where values are greater than some values. I have told you that you must use the Iterator's remove() method for removing mapping while iteration to avoid ConcurrentModificationException, but that's not required anymore in Java 8. From JDK 8 onwards, you can selectively remove mapping without iterating over Map. The JDK 8 API has added several new methods to existing interfaces e.g. java.util.Collection, java.util.Map, Comparator etc because the interface can now contain concrete methods in form of static and default methods.
