The withDays() method of Period Class is used to obtain a period with specified number of days. This number of days is passed as the parameter as integer value.
Syntax:
public Period withDays(int numberOfDays)
Parameters: This method accepts a parameter numberOfDays which is the number of days to be changed in this Period.
Returns: This function returns a Period with the number of days passed as the parameter.
Below is the implementation of Period.withDays() method:
Example 1:
// Java code to demonstrate withDays() method import java.time.Period; class GFG { public static void main(String[] args) { // Get the String to be withDaysd String period = "P1Y2M21D"; // Parse the String into Period Period p = Period.parse(period); System.out.println("Period: " + p); // Get the number of days int numberOfDays = 5; // Change the numberOfDays of this Period // using withDays() method System.out.println("New Period: " + p.withDays(numberOfDays)); }} |
Output:
Period: P1Y2M21D New Period: P1Y2M5D
Example 2:
// Java code to demonstrate withDays() method import java.time.Period; class GFG { public static void main(String[] args) { // Get the String to be withDaysd String period = "-P1Y2M21D"; // Parse the String into Period Period p = Period.parse(period); System.out.println("Period: " + p); // Get the number of days int numberOfDays = -5; // Change the numberOfDays of this Period // using withDays() method System.out.println("New Period: " + p.withDays(numberOfDays)); }} |
Output:
Period: P-1Y-2M-21D New Period: P-1Y-2M-5D
