The Tutorial wants to describe you a code that helps you in creating a Interface in java. Interface is defined as group of method, that implement a empty body. An example of Radio Tuner, when a listener switch on Radio Tuner, the tuner act  as interface between the electrical wing circuit inside the radio and you. Usually the Java do not support multiple inheritance, Interface in java is used for multiple inheritance.

Understand with Example

The given below code illustrates that interface in java support  multiple inheritance In order to implement interface we implement a keyword implement. The Tutorial  describes how to create and use interface method in your class. The step involved in the program are described below-

1)We have taken an interface check ,that implement a empty method message ( ).

2)Inside the class we create an object of interface check and implement a body  to the method message.

3)The object t call and expose a message ( ) method to the outside world.

4)In case there is an exception in the try block, the subsequent catch block handle the exception.

Interface.java

interface check {
public void message();
}
public class Interface {
public static void main(String[] args) {
  try {
  check t = new check() {
  public void message() {
  System.out.println("Method defined in the interface");
  }
  };
  t.message();
  } catch (Exception ex) {
  System.out.println("" + ex.getMessage());
  }
  }
  }
