• getUnits() method is available in java.time package.

  getUnits()方法在java.time包中可用。

• getUnits() method is used to get the List object that contains the units of seconds and Nanos of this Duration.

  getUnits()方法用于獲取List對(duì)象，該對(duì)象包含此Duration的秒數(shù)和Nanos的單位。

• getUnits() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  getUnits()方法是一個(gè)非靜態(tài)方法，只能通過(guò)類對(duì)象訪問(wèn)，如果嘗試使用類名稱訪問(wèn)該方法，則會(huì)收到錯(cuò)誤消息。

• getUnits() method does not throw an exception at the time of returning a list of units.

  返回單元列表時(shí)， getUnits()方法不會(huì)引發(fā)異常。

Parameter(s):

參數(shù)：

  沒(méi)有

Return value:

返回值：

The return type of this method is List, it returns a list of seconds and nanos units from this Duration.

此方法的返回類型為L(zhǎng)ist ，它從該Duration中返回秒和納秒單位的列表。

Example:

例：

// Java program to demonstrate the example // of List getUnits() method of Durationimport java.time.*; import java.util.*; import java.time.temporal.*;public class GetUnitsOfDuration {public static void main(String args[]) {// Instantiates two Duration objectsDuration du1 = Duration.ofHours(1);Duration du2 = Duration.parse("P1DT24H60M60S");// Display du1 and du2System.out.println("du1: " + du1);System.out.println("du2: " + du2);// get a list of units supported // by this Duration du1List list_of_units = du1.getUnits();// Display list_of_unitsSystem.out.println("du1.getUnits(): " + list_of_units);// gets a list of units supported // by this Duration du2list_of_units = du2.getUnits();// Display list_of_unitsSystem.out.println("du2.getUnits(): " + list_of_units);} }

Output

輸出量

du1: PT1H du2: PT49H1M du1.getUnits(): [Seconds, Nanos] du2.getUnits(): [Seconds, Nanos]
