What is Overloading in Java?

When a class has two or more methods by the same name but different parameters, at the time of calling based on the parameters passed respective method is called (or respective method body will be bonded with the calling line dynamically). This mechanism is known as method overloading.

Example

 Live Demo

public class Sample{
   public static void add(int a, int b){
      System.out.println(a+b);
   }
   public static void add(int a, int b, int c){
      System.out.println(a+b+c);
   }
   public static void main(String args[]){
      Sample obj = new Sample();
      obj.add(20, 40);
      obj.add(40, 50, 60);
   }
}

Output

60
150
