class ParentClass { // fields (variables)

// methods }

class ChildClass extends ParentClass { // additional fields

// additional methods }

One child class inherits from one parent class.

public class Animal { public void eat () { System . out . println ( "Eating" ); } }

public class Dog extends Animal { public void bark () { System . out . println ( "Barking" ); } }

public class Animal { public void eat () { System . out . println ( "Eating" ); } }

public class Dog extends Animal { public void bark () { System . out .…
