Java 中的 LocalTime minusMinutes()方法，示例

原文:https://www . geesforgeks . org/local time-mins minutes-method-in-Java-with-examples/

LocalTime 类的minutations()方法用于从该 LocalTime 中减去指定的分钟数值，并将结果作为 LocalTime 对象返回。这一瞬间是不可改变的。计算大约在午夜进行。

语法:

public LocalTime minusMinutes(long MinutesToSubtract)

参数:该方法接受单个参数分钟减去，即要减去的分钟值，可以是负值。

返回值:该方法根据该时间减去分钟数返回当地时间。

下面的程序说明了 minusMinutes()方法:

程序 1:

// Java program to demonstrate
// LocalTime.minusMinutes() method

import java.time.*;

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

        // create a LocalTime object
        LocalTime time
            = LocalTime.parse("19:34:50.63");

        // print LocalTime
        System.out.println("LocalTime before subtraction: "
                           + time);

        // subtract 55 Minutes using minusMinutes()
        LocalTime value = time.minusMinutes(55);

        // print result
        System.out.println("LocalTime after subtraction: "
                           + value);
    }
}

输出:

LocalTime before subtraction: 19:34:50.630
LocalTime after subtraction: 18:39:50.630

程序二:

// Java program to demonstrate
// LocalTime.minusMinutes() method

import java.time.*;

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

        // create a LocalTime object
        LocalTime time
            = LocalTime.parse("01:00:01");

        // print LocalTime
        System.out.println("LocalTime before subtraction: "
                           + time);

        // subtract 600 Minutes using minusMinutes()
        LocalTime value = time.minusMinutes(600);

        // print result
        System.out.println("LocalTime after subtraction: "
                           + value);
    }
}

输出:

LocalTime before subtraction: 01:00:01
LocalTime after subtraction: 15:00:01
