The minusYears() method of Period class in Java is used to subtract the specified years from given period. This functions operates only on YEARS and does not affect other two MONTHS and DAYS.
Syntax:
public Period minusYears(long yearsToSubtract)
Parameters: This method accepts a single parameter yearsToSubtract which is the number of year to be subtracted from the period.
Returns Value: This method returns a Period based on provided period in the input subtracting the specified number of years. It must not be null.
Exceptions: It throws an ArithmeticException. This exception is caught if numeric overflow occurs.
Below programs illustrate the above method:
Program 1:
// Java code to show the function minusYears()// to subtract the number of years from given periodimport java.time.Period;import java.time.temporal.ChronoUnit;  public class PeriodClass {      // Function to subtract two given periods    static void subtractYears(Period p1, int yearstoSubtract)    {          System.out.println(p1.minusYears(yearstoSubtract));    }      // Driver Code    public static void main(String[] args)    {          // Defining first period        int year = 4;        int months = 11;        int days = 10;        Period p1 = Period.of(year, months, days);          int yearstoSubtract = 8;          subtractYears(p1, yearstoSubtract);    }} |
Output:
P-4Y11M10D
Program 2:
// Java code to show the function minusYears()// to subtract the number of years from given periodimport java.time.Period;import java.time.temporal.ChronoUnit;  public class PeriodClass {      // Function to subtract two given periods    static void subtractYears(Period p1, int yearstoSubtract)    {          System.out.println(p1.minusYears(yearstoSubtract));    }      // Driver Code    public static void main(String[] args)    {          // Defining first period        int year = 4;        int months = 11;        int days = 10;        Period p1 = Period.of(year, months, days);          int yearstoSubtract = -8;          subtractYears(p1, yearstoSubtract);    }} |
Output:
P12Y11M10D
