In the Java interface example above, we can see the way the Car and Motorcycle interfaces extend the Vehicles interface. The Vehicles interface contains two methods: hasWheels() and hasEngine(). Any class that
Example 2:Let us take a real world example for better understanding of interface. Suppose we may want to take a interface called Fly and this interface may have methods like goDown() and goForward(). These methods would not contain any logic (i.e. without any implementation). But each cl...
