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() methodimport java.io.*;import java.util.*;import java.lang.annotation.*;// create a custom Annotation@Retention(RetentionPolicy.RUNTIME)public @interface CustomInterface {}@CustomInterfaceinterface 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( "Class represented by myClass: " + myClass.toString()); // Get the AnnotatedInterfaces // using getAnnotatedInterfaces() method System.out.println( "AnnotatedInterfaces of myClass: " + 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() methodimport 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( "Class represented by myClass: " + myClass.toString()); // Get the AnnotatedInterfaces // using getAnnotatedInterfaces() method System.out.println( "AnnotatedInterfaces of myClass: " + Arrays.toString(myClass .getAnnotatedInterfaces())); }} |
Output:
Class represented by myClass: class Test
AnnotatedInterfaces of myClass: []
