Module 20 -> CalenderControl

Hi Ashish,
I try to print dd/MM/yyyy of the string date using [b:1wm44erd]SimpleDateFormat[/b:1wm44erd] and its working fine but when i change the date format i.e.[b:1wm44erd] SimpleDateFormat sdf = new SimpleDateFormat("MM");[/b:1wm44erd] and print that it display wrong input, same case happen if i want to print only year. So please tell me where i am wrong.
[b:1wm44erd]Code and Screen shot attached :- [/b:1wm44erd]

package Zoho.TestCases;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

import org.testng.annotations.Test;

public class calenderRoughWork {


@Test
public void calenderFunctionality() throws ParseException{

//Date d = new Date();
//System.out.println(d);

String date = "22/12/2000";
SimpleDateFormat sdf = new SimpleDateFormat("MM");
Date d1 = sdf.parse(date);
System.out.println("The selecting date is -- > " + sdf.format(d1));


/*SimpleDateFormat sdf = new SimpleDateFormat("yyyy");
System.out.println(sdf.format(d));*/

}
