LocalDate minusDays() method in Java with Examples

LocalDate minus() method in Java with Examples

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); 
    } 
} 

Output:

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); 
    } 
} 

Output:

LocalDate before subtracting days: 2018-12-24
LocalDate after  subtracting days: 2019-01-08
