now from java 8 you can add default method in your interface, that method(default method in the interface) is present in all the classes that will implement it....
Ex :--
public class Java8Tester
{
public static void main(String args[])
public class Java8Tester { public static void main(String args[]) { Vehicle vehicle = new Car(); vehicle.print(); } }
interface Vehicle
{
} interface Vehicle { default void print() { System.out.println("I am a vehicle!"); } static void blowHorn()
static void blowHorn() { System.out.println("Blowing horn!!!"); } } }
interface FourWheeler
{
interface FourWheeler { default void print() { System.out.println("I am a four wheeler!"); } }
class Car implements Vehicle, FourWheeler
{
} class Car implements Vehicle, FourWheeler { public void print() { Vehicle.super.print(); FourWheeler.super.print(); Vehicle.blowHorn(); System.out.println("I am a car!"); } } }
}
