Java Program to compare dates if a date is before another date
To compare dates if a date is before another date, use the Calendar.before() method.
The Calendar.before() method returns whether this Calendar's time is before the time represented by the specified Object. First, let us set a date which is before the current date
Calendar date1 = Calendar.getInstance(); date1.set(Calendar.YEAR, 2010); date1.set(Calendar.MONTH, 11); date1.set(Calendar.DATE, 20);
Here is our current date
Calendar date = Calendar.getInstance();
Now, use the after() method to compare both the dates as shown in the following example
The following is an example
Example
import java.util.Calendar;
public class Demo {
public static void main(String[] args) {
Calendar date1 = Calendar.getInstance();
date1.set(Calendar.YEAR, 2010);
date1.set(Calendar.MONTH, 11);
date1.set(Calendar.DATE, 20);
java.util.Date dt = date1.getTime();
System.out.println("Date One = "+dt);
Calendar date2 = Calendar.getInstance();
System.out.println("Date Two = " + (date2.get(Calendar.MONTH) + 1) + "-"
+ date2.get(Calendar.DATE) + "-" + date2.get(Calendar.YEAR));
if(date1.before(date2)) {
System.out.println("Date One is before Date Two!");
} else {
System.out.println("Date One is after Date Two!");
}
}
}Output
Date One = Mon Dec 20 06:48:11 UTC 2010 Date Two = 11-23-2018 Date One is before Date Two!
