Static methods are one of the important programming concept in any programming language but unfortunately it is also most misunderstood and misused one. Talking about Java, almost all programmers knows that. static methods belong to the class and non-static methods belong to the objects of the class, but hardly all of them understand what it mean. That's why this is one of the popular weed out question on programming interviews. If a Java programmer doesn't know difference between static and non-static method, he is probably not ready yet, and needs more practice and experience. With half knowledge, making a method static can have serious repercussion , especially in today's heavily multi-threaded Java application. Today, one of my reader message me this question on my Facebook account of Javarevisited, which prompted me to to write this tutorial cum discussion post to give a good explanation or example to clarify the concept. What you have learned is totally find, all we do here is to elaborate your learning by understanding key differences between static methods and instance methods in Java.
