Last Updated : 28 Nov, 2019

The getGenericInterfaces() method of java.lang.Class class is used to get the type of interfaces directly implemented by this entity. This entity can be a class or an interface. The method returns an array of type of interfaces directly implemented by this entity.

Syntax:

public Type[] getGenericInterfaces()

Parameter: This method does not accept any parameter.

Return Value: This method returns an array of type of interfaces directly implemented by this entity.

Below programs demonstrate the getGenericInterfaces() method.

Example 1:

import java.util.*;

public class Test {

`` public static void main(String[] args)

`` throws ClassNotFoundException

`` {

`` Class myClass = Class.forName( "Test" );

`` System.out.println( "Class represented by myClass: "

`` + myClass.toString());

`` System.out.println(

`` "GenericInterfaces of myClass: "

`` + Arrays.toString(

`` myClass.getGenericInterfaces()));

`` }

}

Output:

Class represented by myClass: class Test GenericInterfaces of myClass: []

Example 2:

import java.util.*;

interface Arr {

}

public class Test implements Arr {

`` public static void main(String[] args)

`` throws ClassNotFoundException

`` {

`` Class myClass = Class.forName( "Test" );

`` System.out.println(

`` "GenericInterfaces of myClass: "

`` + Arrays.toString(

`` myClass.getGenericInterfaces()));

`` }

}

Output:

GenericInterfaces of myClass: [interface Arr]
