Multilevel Inheritance in Java

Multilevel Inheritance is said to have taken place when a child class inherits from a parent class and then child class becomes the parent class for another class. This process can do on and on. For example, if class B inherits class A, then class C inherits from class B and similarly class D inherits from class C. Then class D may or may not use the members of all the previous classes.

A Sample Program showing Multilevel Inheritance

class Baby
{  
	void eat()
	{
		System.out.println("eating...");
	}  
}  
	class Sleep extends Baby
	{  
		void dream()
		{
			System.out.println("dreaming...");
		}  
	}  
	class Walk extends Sleep
	{  
		void talk()
		{
			System.out.println("talking...");
		}  
	}  
	
	class Check
{  
	public static void main(String args[])
	{  
	Walk d=new Walk();  
	d.talk();  
	d.dream();  
	d.eat();  
	}
}
