Method overloading in Java

Method Overloading is a feature in which we can create more than one method having the same name and same class but their parameter lists are dissimilar.

Why method overloading?

Assume that you have to execute multiplication of the given numbers but there can be any number of arguments (let’s say either 2 or 3 arguments for simplicity).

In order to achieve this, you can create two methods num2(int, int) and num3(int, int, int) for two and three parameters correspondingly. Programmers may get puzzled as the behavior of both methods are same but they differ by name. However, The superior way to complete this task is by overloading methods. Also, depending upon the argument passed, one of the overloaded methods is called.

How to perform method overloading in Java?

Here are different ways to perform method overloading:

  1.      A number of parameters.
  2.      The data type of parameters.
  3.      The sequence of Data type of parameters.

  2. I simply desired to appreciate you again. I’m not certain the things I might have created without the tactics documented by you relating to such concern. It absolutely was an absolute frustrating scenario for me, however , being able to view the very well-written avenue you handled it made me to jump with contentment. Now i’m thankful for the guidance and as well , expect you realize what a powerful job that you are carrying out training others via your webblog. Most probably you’ve never come across all of us.
