In PHP, you can easily adjust dates — whether to move forward or backward — using a built-in function. By combining strtotime() with date(), you can format and modify dates effortlessly. Here’s a quick example:
$date = strtotime("+1 day", strtotime("2020-02-28"));
echo date("Y-m-d", $date);Difference In Java, you need to define which Object that need to be use for an output on each function or method. But what i have created here is not only increase or decrease Date. So here is the simple code.
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.concurrent.TimeUnit;
/**
* Date Utilization for modifying a Date format
*/
public class DateUtils {
public static String modify(String date, int numberOfDate){
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
Date dateObj = null;
try {
dateObj = formatter.parse(date);
Calendar c = Calendar.getInstance();
c.setTime(dateObj);
c.add(Calendar.DATE, numberOfDate);
dateObj = c.getTime();
return formatter.format(dateObj);
} catch (ParseException e) {
e.printStackTrace();
}
return null;
}
public static Date modify(Date date, int numberOfDate){
Calendar c = Calendar.getInstance();
c.setTime(date);
c.add(Calendar.DATE, numberOfDate);
return c.getTime();
}
public static long diff(Date start, Date end){
long diffInMillies = Math.abs(end.getTime() - start.getTime());
return TimeUnit.DAYS.convert(diffInMillies, TimeUnit.MILLISECONDS);
}
public static String diffWithPad(Date start, Date end, int size){
String format = size < 10 ? "%0" + size + "d" : "%" +size+ "d";
return String.format(format,diff(start,end));
}
}So you may run the code in such way.
@Test
public void testDateModifyString() {
String date = "2024-06-21";
int increment = 1;
String result = DateUtils.modify(date,increment);
logger.info("Date Input = {}, increment = {}, Date result = {} ", date, increment, result);
}The result is..
Date Input = 2024-06-21, increment = 1, Date result = 2024-06-22 More information for date in Java, you might find it here
That’s all folks! Happy coding! 🥰😍
