  • An abstract method is one with only a signature and no implementation body. It is often used to specify that a subclass must provide an implementation of the method. Abstract methods are used to specify interfaces in some computer languages.

    … The following Java code shows an abstract class that needs to be extended:
    abstract class Main {
abstract int rectangle(int h, int w); // abstract method signature
}

    The following subclass extends the main class:

    public class Main2 extends Main {
@Override
int rectangle(int h, int w)
{

    return h * w;
}

    }
