Java Date Comparison

Introduction

• In this blog, I am going to explain the program for the date comparison program in Java

Software Requirements

• Java, Notepad.

Program

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

public class DateComparison {
    private static void DateComparison() {

        Date comparetodaydate  = new Date();
        Date comparedate  = (Date) comparetodaydate.clone();
        Date comparedate1970  = new Date(24L*60L*60L*1000L);

        System.out.println("Comparison of two dates by using the equals() method:");
        System.out.println();
        System.out.println("Today's date:" + comparetodaydate);
        System.out.println("Compairing date:" + comparedate);

        if (comparetodaydate.equals(comparedate)) {
            System.out.println("The two dates are equal");
        }
        else {
            System.out.println("The two dates are not equal");
        }

        System.out.println();
        System.out.println("Comparison of two dates by using the equals() method:");
        System.out.println();
        System.out.println("Today's date:" + comparetodaydate);
        System.out.println("Compairing date:" + comparedate1970);

        if (comparetodaydate.equals(comparedate1970)) {
            System.out.println("The two dates are equal");
        }
        else {
            System.out.println("The two dates are not equal");
        }

        System.out.println();
        System.out.println("Comparison of two dates by using the before() method:");
        System.out.println();
        System.out.println("Today's date:" + comparetodaydate);
        System.out.println("Compairing date:" + comparedate1970);

        if (comparetodaydate.before(comparedate1970)) {
            System.out.println("Today's date comes before the compairing date");
        }
        else {
            System.out.println("Today's date does not come before the compairing date");
        }

        System.out.println();
        System.out.println("Comparison of two dates by using the after() method::");
        System.out.println();
        System.out.println("Today's date:" + comparetodaydate);
        System.out.println("Compairing date:" + comparedate1970);

        if (comparetodaydate.after(comparedate1970)) {
            System.out.println("Today's date comes after the compairing date");
        }
        else {
            System.out.println("Today's date does not come after the compairing date");
            System.out.println();
        }
        System.out.println();
    }

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