Java offsetTime plusHours()方法及示例

OffsetTime类的 plusHours() 方法用于向这个OffsetTime添加指定的小时数，并将结果作为一个OffsetTime对象返回。这个瞬间是不可改变的。计算过程围绕着午夜进行。

语法

public OffsetTime plusHours(long hoursToAdd)

参数： 该方法接受一个参数hoursToAdd，它是要添加的小时值，它可以是一个负值。

返回值： 该方法返回一个基于该时间并加上小时的OffsetTime。

下面的程序说明了plusHours()方法。

程序1 :

// Java program to demonstrate
// OffsetTime.plusHours() method
  
import java.time.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a OffsetTime object
        OffsetTime time
            = OffsetTime.parse("12:16:10+11:00");
  
        // print OffsetTime
        System.out.println("OffsetTime before addition : "
                           + time);
  
        // added 3 hours using plusHours()
        OffsetTime value = time.plusHours(3);
  
        // print result
        System.out.println("OffsetTime after addition : "
                           + value);
    }
}

输出。

OffsetTime before addition : 12:16:10+11:00
OffsetTime after addition : 15:16:10+11:00

程序2

// Java program to demonstrate
// OffsetTime.plusHours() method
  
import java.time.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a OffsetTime object
        OffsetTime time
            = OffsetTime.parse("13:20:15+13:00");
  
        // print OffsetTime
        System.out.println("OffsetTime before addition : "
                           + time);
  
        // added -10 hours using plusHours()
        OffsetTime value = time.plusHours(-10);
  
        // print result
        System.out.println("OffsetTime after addition : "
                           + value);
    }
}

输出。

OffsetTime before addition : 13:20:15+13:00
OffsetTime after addition : 03:20:15+13:00
