Java LocalTime withSecond()用法及代碼示例

LocalTime類的withSecond()方法用於獲取此LocalTime的副本，並將秒數更改為作為此方法的參數傳遞的秒數。此LocalTime的其餘值將保持不變。此實例是不可變的，不受此方法調用的影響。

用法:

public LocalTime withSecond(int second)

參數：此方法接受單個參數秒，該參數代表要在結果中設置的second-of-minute，範圍為0到59。

返回值：此方法基於此時間(請求的秒數)返回LocalTime實例。

異常：如果第二個值無效，則此方法引發異常DateTimeException

以下示例程序旨在說明withSecond()方法：

示例1:

// Java program to demonstrate 
// LocalTime.withSecond() 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 time 
        System.out.println("Old LocalTime: "
                           + time); 
  
        // Get a new LocalDateTime with seconds 4 
        LocalTime newtime = time.withSecond(4); 
  
        // print result 
        System.out.println("New LocalDateTime: "
                           + newtime); 
    } 
}

輸出：

Old LocalTime: 19:34:50.630
New LocalDateTime: 19:34:04.630

示例2:

// Java program to demonstrate 
// LocalTime.withSecond() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a LocalTime object 
        LocalTime time 
            = LocalTime.parse("01:21:30.13"); 
  
        // print time 
        System.out.println("Old LocalTime: "
                           + time); 
  
        // Get a new LocalDateTime with seconds 23 
        LocalTime newtime = time.withSecond(23); 
  
        // print result 
        System.out.println("New LocalDateTime: "
                           + newtime); 
    } 
}

輸出：

Old LocalTime: 01:21:30.130
New LocalDateTime: 01:21:23.130
