Java Year from()用法及代碼示例

Year類的from()方法用於從作為參數傳遞的TemporalAccessor對象中獲取Year的實例。 TemporalAccessor表示日期和時間信息的任意集合，此方法有助於根據指定的TemporalAccessor對象獲取年份對象。

用法:

public static Year from(TemporalAccessor temporal)

參數：該方法接受作為時間對象的時間作為參數。它不能為空。

返回值：此方法返回年份對象。

異常：此方法引發以下異常：

DateTimeException-如果無法轉換為年份。

以下示例程序旨在說明from()方法：
示例1:

// Java program to demonstrate 
// Year.from() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a temporal object 
        LocalDate date = LocalDate.parse("2007-12-03"); 
  
        // print instance 
        System.out.println("LocalDate :"
                           + date); 
  
        // apply from method of Year class 
        Year year = Year.from(date); 
  
        // print instance 
        System.out.println("Year get from"
                           + " method: "
                           + year); 
    } 
}

輸出：

LocalDate :2007-12-03
Year get from method: 2007

示例2:

// Java program to demonstrate 
// Year.from() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
        // create a temporal object 
        LocalDate ins = LocalDate.parse("2018-11-27"); 
  
        // print instance 
        System.out.println("LocalDate :"
                           + ins); 
  
        // apply from method of Year class 
        Year year = Year.from(ins); 
  
        // print instance 
        System.out.println("Year get from"
                           + " method: "
                           + year); 
    } 
}

輸出：

LocalDate :2018-11-27
Year get from method: 2018
