Abstract Method in Java

A method which is declared as abstract and does not have implementation is known as an abstract method. Example of abstract method: abstract void printStatus();. Following is the example of Abstract class that has an abstract method

$\begin{lstlisting} abstract class Bike{ abstract void run(); } class Honda4 ... ...String args[]){ Bike obj = new Honda4(); obj.run(); } } \end{lstlisting}$

Output:

$\begin{lstlisting} running safely \end{lstlisting}$

In this example, Bike is an abstract class that contains only one abstract method run. Its implementation is provided by the Honda class.
