Getting the implemented Interfaces

In this section you will learn how to retrieve an Interface (that included in the program) by using the getInterfaces() method. Here is an example that provides the usage of the getInterfaces() method in more detail.

Create an object of class Finterface and assign it with java.util.Integer.class.. Now retrieve Interfaces (included in the program) and store their references in an array of class Class by using the getInterfaces() method.

Here is the code of the Example :

Finterface.java:


import java.lang.reflect.*;



public class Finterface {

  public static void main(String str[]){

  Class cls = java.util.List.class;

  Class[] intfs = cls.getInterfaces();

  int len = intfs.length;

  for (int i =0; i < len; i++)

  {

  System.out.println(intfs[i]);

  }



  }

}

Here is the output of this Example :

C:\roseindia>javac Finterface.java

C:\roseindia>java Finterface
interface java.util.Collection
