Java ChronoPeriod getUnits()用法及代码示例

Java中ChronoPeriod类的getUnits()方法用于获取此ChronoPeriod支持的单位集。列表中支持的单位是YEARS，MONTHS，DAYS(仅按此顺序)。

用法:

List getUnits()

参数：此方法不接受任何参数。

返回值此方法返回包含年，月和日的列表。

以下示例程序旨在说明上述方法：

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：

[Years, Months, Days]
