Java中的 ChronoUnit isTimeBased() 方法及示例

ChronoUnit 枚举isTimeBased()方法用于检查此 ChronoUnit 是否为时间单位。从纳秒到半天的所有 ChronoUnit 都是基于时间的。

句法:

public boolean isTimeBased()

参数:此方法不接受任何内容。

返回值:如果是时间单位,该方法返回true ,如果是数据单位,则返回false

下面的程序说明了 ChronoUnit.isTimeBased() 方法:
方案一:

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

方案二:

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