Comparing Date Having Different Month for Equality Example

The following example shows the usage of Java Date equals() method. We're creating two Date instances of different dates. Each date is compared using equals() method and result is printed.

package com.tutorialspoint;

import java.util.Date;

public class DateDemo {
   public static void main(String[] args) {

      // create a date
      Date date1 = new Date(122, 10, 4);
      Date date2 = new Date(122, 11, 4);

      System.out.println("Date1: " + date1.toString());
      System.out.println("Date2: " + date2.toString());

      boolean result = date1.equals(date2);
      if( result ) {
         System.out.println("Dates are same.");
      } else {
         System.out.println("Dates are not same.");
      } 
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Date1: Fri Nov 04 00:00:00 IST 2022

Comparing Date Having Same time for Equality Example

The following example shows the usage of Java Date equals() method. We're creating two Date instances of same date. Each date is compared using equals() method and result is printed.

package com.tutorialspoint;

import java.util.Date;

public class DateDemo {
   public static void main(String[] args) {

      // create a date
      Date date1 = new Date(122, 11, 5);
      Date date2 = new Date(122, 11, 5);

      System.out.println("Date1: " + date1.toString());
      System.out.println("Date2: " + date2.toString());

      boolean result = date1.equals(date2);
      if( result ) {
         System.out.println("Dates are same.");
      } else {
         System.out.println("Dates are not same.");
      } 
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Date1: Mon Dec 05 00:00:00 IST 2022
