Java 中基于时间单位的()方法，示例

原文:https://www . geesforgeks . org/chronounit-istimebased-method-in-Java-with-examples/

计时单位枚举的 isTimeBased() 方法用于检查该计时单位是否为时间单位。从纳米到半日的所有计时单位都是基于时间的。

语法:

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，该方法返回真，如果是数据单位，则返回假。

下面的程序说明了基于计时单位的()方法: 程序 1:

// 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);
    }
}

Output:

NANOS is Date based attribute:true

程序 2:

// 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);
    }
}

Output:

DAYS is Date based attribute:false
