Class getAnnotatedInterfaces() method in Java with Examples

Last Updated : 28 Jan, 2022

The getAnnotatedInterfaces() method of java.lang.Class class is used to get the superinterface type annotations present in this class. The method returns an array of annotations present.
Syntax:

public Annotation[] getAnnotatedInterfaces()

Parameter: This method does not accepts any parameter.
Return Value: This method returns an array of superinterface type annotations present.
Below programs demonstrate the getAnnotatedInterfaces() method.
Example 1:

Java

// Java program to demonstrate
// getAnnotatedInterfaces() method

import java.io.*;
import java.util.*;
import java.lang.annotation.*;

// create a custom Annotation
@Retention(RetentionPolicy.RUNTIME)
public @interface CustomInterface {
}

@CustomInterface
interface CustomInterfaceImp {}

class Test implements CustomInterfaceImp{

    public Object obj;

    public static void main(String[] args)
        throws ClassNotFoundException
    {

        // returns the Class object for this class
        Class myClass = Test.class;

        System.out.println(
            &quot;Class represented by myClass: &quot;
            + myClass.toString());

        // Get the AnnotatedInterfaces 
        // using getAnnotatedInterfaces() method
        System.out.println(
                &quot;AnnotatedInterfaces of myClass: &quot;
            + Arrays.toString(myClass
                .getAnnotatedInterfaces()));
    }
}

Output:

Class represented by myClass: class Test
AnnotatedInterfaces of myClass: [sun.reflect.annotation.AnnotatedTypeFactory$AnnotatedTypeBaseImpl@4aa298b7]

Example 2:

Java

// Java program to demonstrate
// getAnnotatedInterfaces() method

import java.io.*;
import java.util.*;
import java.lang.annotation.*;

class Test{

    public Object obj;

    public static void main(String[] args)
        throws ClassNotFoundException
    {

        // returns the Class object for this class
        Class myClass = Test.class;

        System.out.println(
            &quot;Class represented by myClass: &quot;
            + myClass.toString());

        // Get the AnnotatedInterfaces
        // using getAnnotatedInterfaces() method
        System.out.println(
                &quot;AnnotatedInterfaces of myClass: &quot;
            + Arrays.toString(myClass
                .getAnnotatedInterfaces()));
    }
}
