Hierarchical Inheritance Example

When two or more classes inherits a single class, it is known as hierarchical inheritance. In the example given below, Dog and Cat classes inherits the Animal class, so there is hierarchical inheritance.

File: TestInheritance3.java

$\begin{lstlisting} class Animal{ void eat(){System.out.println(''eating...'');}... ... c=new Cat(); c.meow(); c.eat(); //c.bark();//C.T.Error } } \end{lstlisting}$

Output:

$\begin{lstlisting} meowing... eating... \end{lstlisting}$
