Java ChronoField isTimeBased()用法及代码示例

ChronoField枚举的isTimeBased()方法用于检查此ChronoField是否表示时间的组成部分.ChronoField常数从纳秒到am-pm-of-day是基于时间的。

用法:

public boolean isTimeBased()

参数：此方法不接受任何内容。

返回值：如果它是时间的一部分，则此方法返回true。

以下示例程序旨在说明ChronoField.isTimeBased()方法：
程序1:

// Java program to demonstrate 
// ChronoField.isTimeBased() 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 isTimeBased() 
        boolean isTimeBasedAttribute 
            = chronoField.isTimeBased(); 
  
        // print 
        System.out.println( 
            "HOUR_OF_DAY"
            + " is Time based attribute:"
            + isTimeBasedAttribute); 
    } 
}

输出：

HOUR_OF_DAY is Time based attribute:true

程序2:

// Java program to demonstrate 
// ChronoField.isTimeBased() method 
  
import java.time.temporal.ChronoField; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // get chronoField 
        ChronoField chronoField 
            = ChronoField.valueOf("YEAR_OF_ERA"); 
  
        // apply isTimeBased() 
        boolean isTimeBasedAttribute 
            = chronoField.isTimeBased(); 
  
        // print 
        System.out.println("YEAR_OF_ERA"
                           + " is Time based attribute:"
                           + isTimeBasedAttribute); 
    } 
}

输出：

YEAR_OF_ERA is Time based attribute:false
