Adding time span example

     

In this example java program we have added the two time spans with the use of add() method of Calendar class which is available in the java.util package. We can add the time spans with the use of add() method which takes two arguments, first is the field and another is amount.

In our java program we have created an object of Calendar by calling constructor of GregorianCalendar with the date 10 October 2008. Now suppose we want to add 2 Months in this time span with the use of add() method . This can be done as follows:

 calendar.add(Calendar.MONTH,2);

Where Calendar.MONTHS represents integer value for Months.

Here is the example code of AddTimeSpan.java as follows:

AddTimeSpan.java

 import java.text.*;
 import java.util.Calendar;
 import java.util.GregorianCalendar; 

 public class AddTimeSpan
 {
  public static void main(String[] args)
  {
  // set calendar to 10 Oct 2008
  Calendar calendar = new GregorianCalendar(2008,Calendar.OCTOBER,10);
  System.out.println("Before Addition date is: ");
  SimpleDateFormat formatter = new SimpleDateFormat("d-MMMM-yyyy hh:mm");
  System.out.println(formatter.format(calendar.getTime()));
 
  System.out.println("Adding 2 Months ");
 // add 2 Months  
 calendar.add(Calendar.MONTH,2);
 
  // Printing date after 2 Months
 System.out.println("After Addition date is: ");
 formatter = new SimpleDateFormat("d-MMMM-yyyy hh:mm");
 System.out.println(formatter.format(calendar.getTime()));
 }  
 }

Output:

C:\DateExample>javac AddTimeSpan.java

C:\DateExample>java AddTimeSpan
Before Addition date is:
10-October-2008 12:00
Adding 2 Months
After Addition date is:
10-December-2008 12:00
