Can a Non Static Method Access a Static Variable/Method in Java?

"Can a non-static method access a static variable or call a static method" is one of the frequently asked questions on the static modifier in Java, the answer is, Yes, a non-static method can access a static variable or call a static method in Java. There is no problem with that because of static members i.e. both static variable and static methods belongs to a class and can be called from anywhere, depending upon their access modifier.

10 Tools Used by Java Programmers in Day to day life

Every trade has their tools, and Java programming is no exception. In fact, good knowledge of tools and mastery of using them, saves a lot of time in design, development, testing, debugging, and troubleshooting any production issue.

Many developers think that learning an IDE like Eclipse, NetBeans or IntelliJ IDEA is enough, but that's just the start of the process. No doubt that IDEs are the most important tool ever created for programmers but they are not the solution for everything.

Top 5 Online Training Courses to Learn Vue.js JavaScript Framework

After Angular and React.js changed the frontend development space, I thought that they are going to rule the frontend world for many years and no more frameworks will come close, but, like many of you, I was wrong; the Vue.js was knocking the door. To be honest, I ignored Vue.js for a long time, hoping that it will slowly fade away, but again I was wrong, Vue.js was not just knocking the door, it was there to stay. So, what does Vue.js offer which Angular and React doesn't? Why should a JavaScript or front-end developer learn Vue.js if he already knows Angular, and React? Well, these are the same questions I asked myself and my friends when I started thinking about Vue.js seriously.

How Http Basic Authentication works in Spring Security?

In the last article, you have learned how to enable Http basic authentication in Spring security-based Java application, and now we'll go one step further to understand how exactly http basic authentication works in Spring security.

The header is aptly named as "Authorization" and it contains based 64 encoded string which is created by concatenating username and password using a colon. For example, if the username is "johnsmith" and password is "JOHN3214" then they will be concatenated as "johnsmith:JOHN3214" before encoded using base 64 encoding algorithms.

Top 30 Java Phone Interview Questions Answers for Freshers, 1 to 2 Years Experienced

Hello guys and ladies, in this article, I am sharing 30 core Java technical questions, from screening and phone round of interviews. In telephonic interviews, questions are short, fact-based and Interviewer expects a to-the-point reply and some keywords in answers.

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 go 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 write a C like Sizeof function in Java?

If you have just started learning Java and came from C background then you might have noticed some difference between Java and C programming language, e.g., String is an object in Java and not a NULL-terminated character array. Similarly, there is is no sizeof() operator in Java. All primitive values have predefined size, e.g., int is 4 bytes, char is 2 byte, short is 2 byte, long and float is 8 byte and so on. But if you are missing sizeOf operator then why not let's make it a coding task? If you are Ok, then your next job is to write a method in Java, which can behave like sizeOf() operator/function of C and returns the size in bytes for each primitive numeric types, i.e. all primitive types except boolean.

Top 6 Books to Learn and Master Programming and Coding - Must Read, Best of Lot

Coding is an integral part of Programming, and we all somehow learned to code by following examples here and there. Yes, I am talking about both self-taught programmer and Computer Science Graduates.

You can easily find programmers in Java, C++, Ruby or Python, but finding programmers, who are also a good coder is very difficult. Some universities have a good curriculum and practical classes to teach coding better than others, but most of these great coders are self-taught Programmers, who learned by reading books, joining online courses and doing things by their own.

How Programmers can Make Money by creating online Courses - Learn and Earn

In last a couple of weeks, I have written some articles about what Java developer should learn in 2019 e.g. programming languages, libraries, and frameworks, but if you have just one thing to improve or learn then that must be your automation testing skills. Testing is one of the disciplines which separates professional developers with amateur ones. It's not about following TDD, BDD, or whatever testing methodologies but at the very minimum level, you must write code to test your code automatically. Many Java developers write unit tests and integration tests which automatically run during build time, mostly by using continuous integration tools like Jenkins or TeamCity.
