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( "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() 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( "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: []
