Java Reflection - Class.isAnnotation() Examples

Java Reflection Java Java API

Class:

java.lang.Class

Method:

public boolean isAnnotation()

Returns:: true if this class object represents an annotation type; false otherwise. Note that if this method returns true, Class.isInterface() would also return true, as all annotation types are also interfaces.

Examples

package com.logicbig.example.clazz;

public class IsAnnotationExample {

public static void main(String... args) {
    Class<Deprecated> c = Deprecated.class;
    System.out.println("isAnnotation: "+c.isAnnotation());
    System.out.println("isInterface: "+c.isInterface());
  }
}

Output

isAnnotation: true
isInterface: true

package com.logicbig.example.clazz;

public class IsAnnotationExample2 {

    public static void main(String... args) {
        Class<Runnable> c = Runnable.class;
        System.out.println("isAnnotation: " + c.isAnnotation());
        System.out.println("isInterface: " + c.isInterface());
    }
}

Output

isAnnotation: false
isInterface: true
