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
