The minusWeeks() method of a LocalDate class in Java is used to subtract the number of specified week from this LocalDate and return a copy of LocalDate.For example, 2018-12-24 minus one week would result in 2018-12-17. This instance is immutable and unaffected by this method call.
Syntax:
public LocalDate minusWeeks(long weeksToSubtract)
Parameters: This method accepts a single parameter weeksToSubtract which represents the weeks to subtract, may be negative.
Return Value: This method returns a LocalDate based on this date with the weeks subtracted, not null.
Exception: This method throws DateTimeException if the result exceeds the supported date range.
Below programs illustrate the minusWeeks() method:
Program 1:
// Java program to demonstrate// LocalDate.minusWeeks() method import java.time.*; public class GFG { public static void main(String[] args) { // create a LocalDate object LocalDate date = LocalDate.parse("2018-12-26"); // print instance System.out.println("LocalDate before" + " subtracting weeks: " + date); // subtract 2 weeks LocalDate returnvalue = date.minusWeeks(2); // print result System.out.println("LocalDate after " + " subtracting weeks: " + returnvalue); }} |
LocalDate before subtracting weeks: 2018-12-26 LocalDate after subtracting weeks: 2018-12-12
Program 2:
// Java program to demonstrate// LocalDate.minusWeeks() 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 weeks: " + date); // subtract -13 weeks LocalDate returnvalue = date.minusWeeks(-13); // print result System.out.println("LocalDate after " + " subtracting weeks: " + returnvalue); }} |
LocalDate before subtracting weeks: 2018-12-24 LocalDate after subtracting weeks: 2019-03-25
