Example to create Interface in java
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());
}
}
}
