Date as double digit

Question

I've a code to get year, month and day for one of my application.

    package com.cera.hyperionUtils;
import java.util.*;

public class HypDate {

 public static int curdate(int field)
 {
  //1. Specify integer 1 for YEAR, 2 for MONTH, 5 DAY_OF_MONTH
  Calendar c = new GregorianCalendar();
  c.setLenient(true); //Allow overflow

  //2. Extract and Return result
   if (field == 2) {
    field = c.get(Calendar.MONTH) + 1;
  }   
  return c.get(field);
 }

 public static void main(String[] args)
 {
 System.out.println(HypDate.curdate(2));

 }
} 

But when i pass 2 it is giving 0 year and day prints correctly.....Also i was trying to make month as double digit. (like 01 for 1)

Can someone please help me....? (I''m very new to java coding)

Answer 1

Rather than returning these one by one, you may just want to use a SimpleDateFormat to format it.

Say I want a date as year-month-day:

// Necessary imports
import java.text.DateFormat;
import java.text.SimpleDateFormat;

// Declare class and stuff before this

public static String getFormattedDate() {
    DateFormat df = new SimpleDateFormat("yyyy-MM-dd");

    return df.format(new Date());
}

public static void main(String[] args) {
    System.out.println(getFormattedDate());
}

Outputs 2010-10-29

Edit:

Since you just want the month, you can do this:

public static String getFormattedMonth() {
    DateFormat df = new SimpleDateFormat("MM");

    return df.format(new Date());
}
