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(24 L * 60 L * 60 L * 1000 L);
  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();
 }
}
