參數：此方法不接受任何內容。

返回值：此方法返回一個數組，該數組包含此枚舉類型的常量，並按順序聲明它們。

以下示例程序旨在說明ChronoField.values()方法：
程序1:

// Java program to demonstrate 
// ChronoField.values() method 
  
import java.time.temporal.ChronoField; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // get chronoField 
        ChronoField chronoField 
            = ChronoField.valueOf("HOUR_OF_DAY"); 
  
        // apply values() 
        ChronoField[] array 
            = chronoField.values(); 
  
        // print 
        for (int i = 0; i < array.length; i++) 
            System.out.println(array[i]); 
    } 
}

輸出：

NanoOfSecond

程序2:

// Java program to demonstrate 
// ChronoField.values() method 
  
import java.time.temporal.ChronoField; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // get chronoField 
        ChronoField chronoField 
            = ChronoField.valueOf("HOUR_OF_DAY"); 
  
        // apply values() 
        ChronoField[] array 
            = chronoField.values(); 
  
        // print 
        System.out.println("ChronoField length:"
                           + array.length); 
    } 
}

輸出：

ChronoField length:30
