package com.javacoderanch.example.util;

import java.util.Calendar;

public class LastDayOfMonth {
    public static void main(String[] args) {
	//
	// Get a calendar instance
	//
	Calendar calendar = Calendar.getInstance();
	
	//
	// Get the last date of the current month. To get the last date for a
	// specific month you can set the calendar month using calendar object
	// calendar.set(Calendar.MONTH, theMonth) method.
	//	
	int lastDate = calendar.getActualMaximum(Calendar.DATE);
	
	//
	// Set the calendar date to the last date of the month so then we can
	// get the last day of the month
	//
	calendar.set(Calendar.DATE, lastDate);	
	int lastDay = calendar.get(Calendar.DAY_OF_WEEK);
	
	//
	// Print the current date and the last date of the month
	//
	System.out.println("Last Date: " + calendar.getTime());
	
	//
	// The lastDay will be in a value from 1 to 7 where 1 = monday and 7 =
	// saturday respectively.
	//
	System.out.println("Last Day : " + lastDay);	
    }
