Overloading Method:

Overloading Method can be easily defined by having multiple methods with same name but with different parameter, in a Class. Difference in Parameter can be in number of parameters used in method or change in type of parameter.

For Example:

    class Area{  
      void area(int length,int breadth)
      {
    	  System.out.println(length*breadth);
      }  
      void area(double radius)
      {
    	  System.out.println(3.14*radius*radius);
      }  
      }

But How to overload main():

class Demo
  {  
  public static void main(int a)
  {  
  System.out.println(a);  
  }  
  public static void main(String args[])
  {  
  System.out.println("Overloading main() method");  
  main(50);  
  }  
} 

Output we Obtain is :

Overloading main() method
50
