The minusDays() method of LocalDate class in Java is used to subtract the number of specified day from this LocalDate and return a copy of LocalDate.For example, 2019-01-01 minus one day would result in 2018-12-31. This instance is immutable and unaffected by this method call.
Syntax:
public LocalDate minusDays(long daysToSubtract)
Parameters: This method accepts a single parameter daysToSubtract which represents the days to subtract, may be negative.
Return value: This method returns a LocalDate based on this date with the days subtracted, not null.
Exception: This method throws DateTimeException if the result exceeds the supported date range.
Below programs illustrate the minusDays() method:
Program 1:
// Java program to demonstrate// LocalDate.minusDays() method import java.time.*; public class GFG { public static void main(String[] args) { // create a LocalDate object LocalDate date = LocalDate.parse("2018-11-13"); // print instance System.out.println("LocalDate before" + " subtracting days: " + date); // subtract 17 days LocalDate returnvalue = date.minusDays(17); // print result System.out.println("LocalDate after " + " subtracting days: " + returnvalue); }} |
LocalDate before subtracting days: 2018-11-13 LocalDate after subtracting days: 2018-10-27
Program 2:
// Java program to demonstrate// LocalDate.minusDays() method import java.time.*; public class GFG { public static void main(String[] args) { // create a LocalDate object LocalDate date = LocalDate.parse("2018-12-24"); // print instance System.out.println("LocalDate before" + " subtracting days: " + date); // subtract -15 days LocalDate returnvalue = date.minusDays(-15); // print result System.out.println("LocalDate after " + " subtracting days: " + returnvalue); }} |
LocalDate before subtracting days: 2018-12-24 LocalDate after subtracting days: 2019-01-08
