Method Overloading in Java
Method Overloading in Java
- Two or more methods with the same name under same class, it is called method overloading.
- It example for static polymorphism.
- Binding of the method call, is done during compile time and hence it is called static bindingorearly binding.
- The overloaded methods can differ by the number of arguments or argument type or sequence of the arguments.
Example:
package Mypkg;
public class MethodOverLoadex {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println("Entered MethodOverLoadex Main() ");
myOverloading obj=new myOverloading();
obj.getCal();// method calling
obj.getCal(10,20);
System.out.println("Exited MethodOverLoadex Main() ");
}
}
class myOverloading
{ int num1,num2;// actual paramters
void getCal(int a, int b)// Two input
{
System.out.println("Entered myOverloading getCal(a,b) ");
System.out.println("&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&");
num1=a;
num2=b;
System.out.println("multiplication "+ " => "+ num1*num2);
System.out.println("&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&");
System.out.println("Exited myOverloading getCal(a,b) ");
}
void getCal()// Taking zero input
{
System.out.println("Entered myOverloading getCal() ");
System.out.println("*************************");
num1=100;
num2=200;
System.out.println("Addition "+ " => " + (num1+num2));
System.out.println("*************************");
System.out.println("Exited myOverloading getCal() ");
}
}
Output:
Entered MethodOverLoadex Main() Entered myOverloading getCal() ************************* Addition => 300 ************************* Exited myOverloading getCal() Entered myOverloading getCal(a,b) &&&&&&&&&&&&&&&&&&&&&&&&&&&&&& multiplication => 200 &&&&&&&&&&&&&&&&&&&&&&&&&&&&&& Exited myOverloading getCal(a,b) Exited MethodOverLoadex Main()
