The getInterfaces() method of java.lang.Class class is used to get the interfaces directly implemented by this entity. This entity can be a class or an interface. The method returns an array of interfaces directly implemented by this entity.
Syntax:
public Class<T>[] getInterfaces()
Parameter: This method does not accept any parameter.
Return Value: This method returns an array of interfaces directly implemented by this entity.
Below programs demonstrate the getInterfaces() method.
Example 1:
Java
// Java program to demonstrate getInterfaces() methodimport java.util.*;public class Test { public static void main(String[] args) throws ClassNotFoundException { // returns the Class object for this class Class myClass = Class.forName("Test"); System.out.println("Class represented by myClass: " + myClass.toString()); // Get the interfaces of myClass // using getInterfaces() method System.out.println( "Interfaces of myClass: " + Arrays.toString( myClass.getInterfaces())); }} |
Output:
Class represented by myClass: class Test Interfaces of myClass: []
Example 2:
Java
// Java program to demonstrate getInterfaces() methodimport java.util.*;interface Arr {}public class Test implements Arr { public static void main(String[] args) throws ClassNotFoundException { // returns the Class object Class myClass = Class.forName("Test"); // Get the interfaces of myClass // using getInterfaces() method System.out.println( "Interfaces of myClass: " + Arrays.toString( myClass.getInterfaces())); }} |
Output:
Interfaces of myClass: [interface Arr]
