This is an example of how to compare Dates with after(Object when) method of the Calendar class. Comparing a Calendar object to another using after(Object when) method of Calendar implies that you should:
- Use
getInstance()API method of Calendar, in order to get two Calendar objects, using the default time zone and locale. - Use
set(int field, int value)API method of Calendar, in order to set a future value, e.g. year to one of the calendar objects. - Compare the two calendars, using
after(Object when)method of Calendar. The calendar object that invokes the method is thefutureCalendarin the example and it is set to represent a future date, so it represents a time after the time represented by the other calendar and the method returns true.
Let’s take a look at the code snippet that follows:
package com.javacodegeeks.snippets.core;
import java.util.Calendar;
public class CompareDatesWithAfterMethod {
public static void main(String[] args) {
Calendar currentCalendar = Calendar.getInstance();
Calendar futureCalendar = Calendar.getInstance();
// set calendar to future date
futureCalendar.set(Calendar.YEAR, 2066);
if (futureCalendar.after(currentCalendar)) {
System.out.println(futureCalendar.getTime() + " is after " + currentCalendar.getTime());
}
}
}
Output:
Tue Oct 19 22:54:53 EEST 2066 is after Wed Oct 19 22:54:53 EEST 2011
This was an example of how to compare Dates with after(Object when) method of the Calendar class in Java.
