Period withDays() method in Java with Examples
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
