The getYears() method of Period in Java is used to get the amount of years of this period with which it is used. Note: 15 months is not equal to 1 years and 3 months. Syntax:
public List getYears()
Parameters: This method does not accepts any parameter. Returns: This method returns the amounts of years in this current period. Below programs illustrate the above method: Program 1:Â
Java
// Java code to show the function getYears()// to get the number of years in the periodimport java.time.Period;import java.time.temporal.ChronoUnit;Â
public class PeriodDemo {Â
    // Function to get the number of years    static void getNumberOfDays(int year, int months, int days)    {        Period period = Period.of(year, months, days);        System.out.println(period.getYears());    }Â
    // Driver Code    public static void main(String[] args)    {Â
        int year = 12;        int months = 3;        int days = 31;Â
        getNumberOfDays(year, months, days);    }} |
Output:
12
Program 2:Â
Java
// Java code to show the function getYears()// to get the number of years in the periodimport java.time.Period;import java.time.temporal.ChronoUnit;Â
public class PeriodDemo {Â
    // Function to get the number of years    static void getNumberOfDays(int year, int months, int days)    {        Period period = Period.of(year, months, days);        System.out.println(period.getYears());    }Â
    // Driver Code    public static void main(String[] args)    {Â
        int year = -12;        int months = 3;        int days = 31;Â
        getNumberOfDays(year, months, days);    }} |
Output:
-12
