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 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 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: []
