package com.java2novice.date;

import java.util.Date;

public class MyBeforeDateTest {

	public static void main(String a[]){
		
		Date current = new Date();
		//create a date one day before current date
		long prevDay = System.currentTimeMillis() - 1000*60*60*24;
		//create date object
		Date prev = new Date(prevDay);
		//compare both dates
		if(prev.before(current)){
			System.out.println("The date is older than current day");
		} else {
			System.out.println("The date is future day");
		}
	}
}

The date is older than current day
