Example 1

//import  statements
import java.lang.annotation.Annotation; //import annotation
import java.lang.annotation.Inherited;  //import Inherited 
import java.lang.annotation.Retention; //import retention
import java.lang.annotation.RetentionPolicy;  //import retention  policy


public class ClassgetDeclaredAnnotationExample1 {

    public static void main(String... args) {
   Annotation ann = Class1.class.getDeclaredAnnotation(Deprecated.class); // getdeclaredannotation method
        System.out.println(ann); //print annotation
        ann = Class1.class.getDeclaredAnnotation(Annotation1.class); // getdeclaredannotation method
        System.out.println(ann);        
    }

    @Deprecated
    public static class Class1 extends SuperClass1 {
    }

    @Annotation1
    public static class SuperClass1 {
    }
