isAnnotationPresent returning false

[Jayavardhan geepi]

public @interface ItsJays {
   String value();
   int age();
   float salary();
}

Test class

public class TestItsJays {

	public static void main(String[] args) {

		try {

			for(Method ms:Class.forName("org.gp.annotations.TestItsJays").getMethods()){
				System.out.print(ms.getName()+"-");
				System.out.println(ms.isAnnotationPresent(ItsJays.class));
			}
			
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	
	@ItsJays(value="Some String",age=24,salary=1234.56f)
	public void doesNothing(){
		System.out.println("Really for nothing");
	}

}

Why it is printing false for doesNothing method.
Can anybody trace it out please.
Thanks

You have to annotate your annotation to tell the compiler to keep the annotation in the class file. If you don't, then the compiler will just throw away the annotation and you won't be able to see it at runtime.
