Question

What will be result of each method call in the main method for the codes shown below?

public class Pett public void speak) System.out.println ("speaking!") public void jump) System.out.println ("jumping!") public void walk)i System.out.println ("walking!") public class Dog extends Pet t public class SimpleInheritance i public static void main (String args [1) Dog myDognew Dog ); myDog.speak) myDog.walk) myDog.jump )

Answer 1

Dog myDog = new Dog() // It will create an object for class Dog

myDog.speak() // it will call the speak method in Pet class and hence shows the output speaking

myDog.walk() // it will call the walk method in Pet class and hence shows the output walking

myDog.jump() // it will call the jump method in Pet class and hence shows the output jumping

The output of above program is:

Speaking
walking
jumping
