How to get all annotations from a class?

• Incase if any annotation is specifies its retention policy as RUNTIME, then those annotations can be queried at runtime by any java program.
• Below example code shows how to query all given annotations at runtime.

package com.java2novice.annotations;

import java.lang.annotation.Annotation;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.reflect.Method;


@Retention(RetentionPolicy.RUNTIME)
@interface MyAnnoOne{
	
	String key();
	String value();
}

@Retention(RetentionPolicy.RUNTIME)
@interface MyAnnoTwo{
	
	int count();
}

public class MyMultipleAnns {

	@MyAnnoTwo(count=20)
	@MyAnnoOne(key="site", value="java2novice.com")
	public void myAnnotationTestMethod(){
		
		try {
			Class<? extends MyMultipleAnns> cls = this.getClass();
			Method mth = cls.getMethod("myAnnotationTestMethod");
			Annotation[] anns = mth.getAnnotations();
			for(Annotation an:anns){
				System.out.println(an);
			}
		} catch (SecurityException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (NoSuchMethodException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	
	public static void main(String a[]){
		
		MyMultipleAnns mat = new MyMultipleAnns();
		mat.myAnnotationTestMethod();
	}
}

@com.java2novice.annotations.MyAnnoTwo(count=20)
@com.java2novice.annotations.MyAnnoOne(key=site, value=java2novice.com)
