I need to check if a given date falls in the current month, and I wrote the following code, but the IDE reminded me that the getMonth()
and getYear()
methods are obsolete. I was wondering how to do the same thing in newer Java 7 or Java 8.
private boolean inCurrentMonth(Date givenDate) {
Date today = new Date();
return givenDate.getMonth() == today.getMonth() && givenDate.getYear() == today.getYear();
}
We can use the simple isBefore , isAfter and isEqual to check if a date is within a certain date range; for example, the below program check if a LocalDate is within the January of 2020. startDate : 2020-01-01 endDate : 2020-01-31 testDate : 2020-01-01 testDate is within the date range.
To compare dates if a date is after another date, use the Calendar. after() method.
The now() method of the LocalTime class in Java is used to get the current time from the system clock in the default time-zone.
//Create 2 instances of Calendar
Calendar cal1 = Calendar.getInstance();
Calendar cal2 = Calendar.getInstance();
//set the given date in one of the instance and current date in the other
cal1.setTime(givenDate);
cal2.setTime(new Date());
//now compare the dates using methods on Calendar
if(cal1.get(Calendar.YEAR) == cal2.get(Calendar.YEAR)) {
if(cal1.get(Calendar.MONTH) == cal2.get(Calendar.MONTH)) {
// the date falls in current month
}
}
