Polymorphism

Polymorphism is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object.

Overloading

Methods with the same names in a class are allowed provided each method has a different signature. Overloading can be done in the following ways:

• Number of arguments
• Type of arguments
• Position of arguments

An example of a Java program with overloading

The following is an example of overloading in a Java program:

package MyFirstPackage;

class SampleClass10 {
  void sampleMethod(){
  System.out.println("executing sample method");
}
  void sampleMethod(float b){
    System.out.println("executing sample method" + b);
  }
 }
 
  class SampleClass20 extends SampleClass10 {
    void sampleMethod1(){
    System.out.println("executing sample method 2");
  }
    void sampleMethod1(int a){
    System.out.println("executing sample method 2" + a);
    }
  }
