参数： 该方法接受一个TemporalUnit类型的单参数单位，它是获得所需单位的单位。

返回值： 该函数返回所要求的单位的长值。

异常情况 。

下面的程序说明了上述方法。

程序1 :

// Java code to show the function get()// which gives the requested unit  import java.time.*;import java.time.chrono.*;import java.time.temporal.ChronoUnit;  public class ChronoPeriodDemo {      // Function to get requested unit    static void getUnit(int year, int months, int days)    {        ChronoPeriod period = Period.of(year, months, days);        System.out.println(period.get(ChronoUnit.DAYS));    }      // Driver Code    public static void main(String[] args)    {          int year = 8;        int months = 5;        int days = 25;          getUnit(year, months, days);    }}

输出:

25

程序2

// Java code to show the function get()// which gives the requested unit  import java.time.*;import java.time.chrono.*;import java.time.temporal.ChronoUnit;  public class ChronoPeriodDemo {      // Function to get requested unit    static void getUnit(int year, int months, int days)    {        ChronoPeriod period = Period.of(year, months, days);        System.out.println(period.get(ChronoUnit.YEARS));    }      // Driver Code    public static void main(String[] args)    {          int year = 11;        int months = 3;        int days = 21;          getUnit(year, months, days);    }}

输出:

11
