Java LocalTime plusHours()用法及代碼示例

LocalTime類的plusHours()方法用於將指定的“小時數”值添加到此LocalTime並將結果作為LocalTime對象返回。這一瞬間是一成不變的。計算大約在午夜結束。

用法:

public LocalTime plusHours(long hoursToAdd)

參數：此方法接受單個參數hoursToAdd，它是要添加的小時數的值，它可以是負值。

返回值：此方法基於此時間(加上小時)返回LocalTime。

以下示例程序旨在說明plusHours()方法：

示例1:

// 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); 
    } 
}

輸出：

LocalTime before addition : 19:34:50.630
LocalTime after addition : 22:34:50.630

示例2:

// 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); 
    } 
}

輸出：

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