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

LocalTime 类的 plusMinutes() 方法用于将指定的分钟数值添加到该 LocalTime，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 plusMinutes(long MinutesToAdd)

参数:此方法接受单个参数分钟添加，即要添加的分钟值，可以是负值。

返回值:该方法返回一个基于该时间的本地时间，并加上分钟。

下面的程序说明了 plusMinutes()方法:

程序 1:

// Java program to demonstrate
// LocalTime.plusMinutes() 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 addition: "
                           + time);

        // add 55 Minutes using plusMinutes()
        LocalTime value = time.plusMinutes(55);

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

输出:

LocalTime before addition: 19:34:50.630
LocalTime after addition: 20:29:50.630

程序二:

// Java program to demonstrate
// LocalTime.plusMinutes() 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 addition: "
                           + time);

        // add -600 Minutes using plusMinutes()
        LocalTime value = time.plusMinutes(-600);

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

输出:

LocalTime before addition: 01:00:01
LocalTime after addition: 15:00:01
