Java 中的 OffsetTime isBefore()方法，带示例

原文:https://www . geeksforgeeks . org/offsettime-is before-method-in-Java-with-examples/

Java 格式的 OffsetTime 类的 isBefore() 方法检查传递的时间是否在参数中指定的时间之前。

语法:

public boolean isBefore(OffsetTime other)

参数:此方法接受单个强制参数其他，指定要比较的时间。

返回值:如果日期在过去的日期之前，则返回真，否则返回假。

以下程序说明了 isBefore() 方法:

程序 1 :

// Java program to demonstrate the isBefore() method
import java.time.OffsetTime;

public class GFG {
    public static void main(String[] args)
    {

        // Parses the time
        OffsetTime time1
            = OffsetTime.parse("15:30:30+07:00");

        // Parses the time
        OffsetTime time2
            = OffsetTime.parse("15:20:30+07:00");

        // gets the time1
        System.out.println("time1: "
                           + time1);

        // gets the time2
        System.out.println("time1: "
                           + time2);

        System.out.println("time1 is before time2: "
                           + time1.isBefore(time2));
    }
}

输出:

time1: 15:30:30+07:00
time1: 15:20:30+07:00
time1 is before time2: false

程序二 :

// Java program to demonstrate the isBefore() method

import java.time.OffsetTime;

public class GFG {
    public static void main(String[] args)
    {

        // Parses the time
        OffsetTime time1
            = OffsetTime.parse("15:30:30+07:00");

        // Parses the time
        OffsetTime time2
            = OffsetTime.parse("15:30:30+07:00");

        // gets the time1
        System.out.println("time1: "
                           + time1);

        // gets the time2
        System.out.println("time1: "
                           + time2);

        System.out.println("time1 is before time2: "
                           + time1.isBefore(time2));
    }
}

输出:

time1: 15:30:30+07:00
time1: 15:30:30+07:00
time1 is before time2: false
