Here is the example

interface MyInterface {
 String enter(String name);
 default String exit(String name) {
  return“ Hello” + name + ”, you are using exit method of MyInterface interface”;
 }
}
public class MyClass {
 public static void main(String[] args) {
  MyInterface f1 = new MyInterface() {
   @Override
   public String enter(String name) {
    return“ Hello” + name + ”, you are using enter method of MyInterface interface”;
   }
  };
  System.out.println(f1.enter(“Aman”));
  System.out.println(f1.exit(“Aman”));
 }
}
