Answer the following parts reguarding default methods This i

Answer the following parts reguarding default methods. This is for Java. Program used is NetBeans (I don\'t know if this matters or not)

a) How to create a default method

b) How to use a default method in a class that implements an interface

Solution

\'default\' method is only supported in java 8.
It is created as shown below:

public interface <interface_name> {
   default void method_name(){
       ....
       ....
       ....
   }
}

using a default method in a class that implements an interface:

public class cl implements <interface_name> {
default void method_name(){
        // overriding
}
}
