Java ChronoPeriod getUnits()方法及示例

Java中 ChronoPeriod类 的 getUnits()方法 用于获取该ChronoPeriod所支持的单位集。支持的单位有年、月、日，并列在一个列表中（只按这个顺序）。

语法

List getUnits()

参数： 该方法不接受任何参数。

返回值 该方法返回一个包含年、月、日的列表。

下面的程序说明了上述方法。

程序1 :

// Java code to show the function getUnits()// to get the set of units supported by period  import java.time.*;import java.time.chrono.*;import java.time.temporal.ChronoUnit;  public class ChronoPeriodDemo {      // Function to get the set of units supported by period    static void getNumberOfDays(int year, int months, int days)    {        ChronoPeriod period = Period.of(year, months, days);        System.out.println(period.getUnits());    }      // Driver Code    public static void main(String[] args)    {        int year = 1;        int months = 13;        int days = 36;          getNumberOfDays(year, months, days);    }}

输出:

[Years, Months, Days]

程序2 :

// Java code to show the function getUnits()// to get the set of units supported by period  import java.time.*;import java.time.chrono.*;import java.time.temporal.ChronoUnit;  public class ChronoPeriodDemo {      // Function to get the set of units supported by period    static void getNumberOfDays(int year, int months, int days)    {        ChronoPeriod period = Period.ofDays(days);        System.out.println(period.getUnits());    }      // Driver Code    public static void main(String[] args)    {        int year = 0;        int months = 0;        int days = 0;          getNumberOfDays(year, months, days);    }}

输出:
