Question

Given the following package contents, write a short program (class Insecttest) that demonstrates the concept of polymorphism using the classes provided in JAVA

package insect;

public class Insect {

     public void nickname () {

       System.out.println ("bug");

     }

     }

public class Flying extends Insect {

     @Override

     public void nickname() {

          System.out.println ("flying bug");

     }

     }

public class Jumping extends Insect{

          @Override

          public void nickname() {

               System.out.println ("jumping bug");

          }

          }

Answer 1

The answer to this question is as follows:

The polymorphism is of two types:

1.static polymorphism(Method overloading)

2.Dynamic polymorphism(Method overriding)

From the above question, Dynamic polymorphism is implemented

I am trying to execute all the classes at a time so I removed public for the classes if you want to execute you can save as files like insect.java , flying.java , jumping.java

The code is as follows:

class Insect
{//Declaring the class Insect it is the base class for the remaining

public void nickname()
{
System.out.println("bug");
}
}
class Flying extends Insect
{ //decalring the class Flying that is inherited from the Insect class
@Override //overriding the insect class method
public void nickname()
{
System.out.println("flying bug");
}
  
}
class Jumping extends Insect
{//decalring the class Jumping that is inherited from the Insect class
@Override//overriding the insect class method
public void nickname()
{
System.out.println("jumping bug");
}
  
}

public class Test{

public static void main(String[] args){
//Overiding the method that is insect with the method in Flying
Insect insect1=new Flying();
insect1.nickname();
//Overiding the method that is insect with the method in jumping
Insect insect2=new Jumping();
insect2.nickname();
//calling the method in the insect class
Insect insect3=new Insect();
insect3.nickname(); // prints Vehicles can move!!

}

}
