Dive into Java Method Overloading

Method overloading allows a class to have two or more methods having same name. But there are some conditions applied if you overload a method. Let’s discuss on then.

First of all we should know “ Why do we use method overloading in Java?” .

Suppose we have to perform addition of given number but there can be any number of arguments, if we write method such as methodAddTwoNo(int a, int b) for two arguments, methodAddThreeNo(int a, int b, int c) for three arguments then it is very difficult for you and other programmer to understand purpose or behaviors of method they can not identify purpose of method. So we use method overloading to easily figure out the program. For example above two methods we can write sum(int a, int b) and sum(int a, int b, int c) using method overloading concept.

So it is clear that to achieve method overloading concept methods should have same name but with different parameters.

But what will happen if we put methods name same and also the same parameters.

Let’s see: Continue reading
