Compare date time using after() method of Java Calendar

The Calendar.after() method returns whether this Calendar's time is after the time represented by the specified Object.

First, let us set a date which is after (future date) the current date

Calendar afterDate = Calendar.getInstance();
afterDate.set(Calendar.YEAR, 2025);
afterDate.set(Calendar.MONTH, 05);
afterDate.set(Calendar.DATE, 30);

Here is our date, which is 11-22-2018

Calendar currentDate = Calendar.getInstance();

Now, use the after() method to compare both the dates as shown in the following example

Example

 Live Demo

import java.util.Calendar;
public class Demo {
   public static void main(String[] args) {
      Calendar afterDate = Calendar.getInstance();
      afterDate.set(Calendar.YEAR, 2025);
      afterDate.set(Calendar.MONTH, 05);
      afterDate.set(Calendar.DATE, 30);
      java.util.Date dt = afterDate.getTime();
      System.out.println("Future Date = "+dt);
      Calendar currentDate = Calendar.getInstance();
      System.out.println("Current date = " + (currentDate.get(Calendar.MONTH) + 1) + "-"
         + currentDate.get(Calendar.DATE) + "-" + currentDate.get(Calendar.YEAR));
      System.out.println("Date "+dt+ " is after current date? = " + afterDate.after(currentDate));
   }
}

Output

Future Date = Mon Jun 30 12:36:27 UTC 2025
Current date = 11-22-2018
Date Mon Jun 30 12:36:27 UTC 2025 is after current date? = true
