Java中的 LocalTime plusHours() 方法及示例

LocalTimeplusHours()方法用于将指定的 Hours 值添加到此 LocalTime 并将结果作为 LocalTime 对象返回。这个瞬间是不变的。计算在午夜左右结束。

句法:

public LocalTime plusHours(long hoursToAdd)

参数:此方法接受单个参数hoursToAdd ,它是要添加的小时的值,它可以是负值。

返回值:此方法基于此时间返回一个LocalTime ,并添加小时数。

下面的程序说明了 plusHours() 方法:

方案一:

// Java program to demonstrate
// LocalTime.plusHours() 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);
  
        // added 3 hours using plusHours()
        LocalTime value = time.plusHours(3);
  
        // print result
        System.out.println("LocalTime after addition : "
                           + value);
    }
}
输出:
LocalTime before addition : 19:34:50.630
LocalTime after addition : 22:34:50.630

方案二:

// Java program to demonstrate
// LocalTime.plusHours() 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);
  
        // added -10 hours using plusHours()
        LocalTime value = time.plusHours(-10);
  
        // print result
        System.out.println("LocalTime after addition : "
                           + value);
    }
}
输出:
LocalTime before addition : 01:00:01
LocalTime after addition : 15:00:01
