		System.out.println("Rectangle create with following properties: ");
		System.out.println("Length: " + defaultLength);
		System.out.println("Width: " + defaultWidth);
	}
 
}

ReflectionTest.java

package com.codesjava;
 
import java.util.Arrays;
 
public class ReflectionTest {
	public static void main(String args[]){
		try {
			Class c=Class.forName("com.codesjava.Rectangle");  
			System.out.println(Arrays.toString(c.getAnnotations()));
		} catch (Exception e) {
