Java中的 ChronoUnit isDateBased() 方法及示例

ChronoUnit 枚举isDateBased()方法用于检查此 ChronoUnit 是否为日期单位。从天到时代的所有 ChronoUnit 都是基于日期的。

句法:

public boolean isDateBased()

参数:此方法不接受任何内容。

返回值:如果是日期单位,则该方法返回true ,如果是时间单位,则返回false

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

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

方案二:

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