如何在我的代码行中正确设置 totalSeconds() （时分秒）和 return

Question

大家好，我的老师给了我一个时钟程序，它必须 return 信息等，到目前为止我对总秒数应该如何工作有点困惑，我会展示我的 driver 和下面的正常文件，请帮助。我必须确保总秒数的时分秒数 return。我将 post 对我的代码进行实时编辑

我尝试通过添加一个变量并将其添加到 driver 中来 [=22=] 它，但无济于事。

{

  //Instance Variables
  private int Hours;
  private int Minutes;
  private int Seconds;
  private double Cost;
  private boolean IsOn;
  private int DLS;



  //Zero arg constructors
  public Clock()
  { // Start
    Hours = 10;
    Minutes = 52;
    Seconds = 23;   
    Cost = 20.00;
    IsOn = true;
    DLS = 11;
  } // End

  //Multi-Argument Constructors

  public Clock( int Hours, int Minutes, int Seconds, double Cost , boolean IsOn, int DSL)
  { // Start
    this.Hours = Hours;
    this.Minutes = Minutes;
    this.Seconds = Seconds;
    this.Cost = Cost;
    this.IsOn = IsOn;
    this.DLS = DLS;
  } // End

  public void setTime(int Hours)
  {
    System.out.println(Hours + 1);
  }

  public int convertDaylightSaving(int Hours)
  {
    return Hours;
  }



  //ToString Method

  public String toString()
  { //Start
    String output;
    output = "When I checked my watch the hour was: " + Hours + "\n" + 
      "When I checked my watch the minute was: " + Minutes + "\n" +
      "When I checked my watch the seconds were: " + Seconds + "\n" +
      "The Cost is: " + Cost + "\n" +
      "Is this the time right now?: " + IsOn;

    return output;

  }
} // End

public class ClockDriver
{ 
 public class ClockDriver
{ // Start

  public static void main(String[] args)
  { // Officially Start

    Clock Watch = new Clock( 11, 04, 16, 35.99, false, 11);
    System.out.println(Watch);
  } // End
} // Officially End

预期的结果是把我做的都打印出来，结果报错

好的，我实际上通过执行以下操作回答了我自己的问题。



public class Clock
{

  //Instance Variables
  private int Hours;
  private int Minutes;
  private int Seconds;
  private double Cost;
  private boolean IsOn;
  private int DLS;
  int totalSeconds; 



  //Zero arg constructors
  public Clock()
  { // Start
    Hours = 10;
    Minutes = 52;
    Seconds = 23;   
    Cost = 20.00;
    IsOn = true;
    DLS = 11;
    totalSeconds = 9945;
  } // End

  //Multi-Argument Constructors

  public Clock( int Hours, int Minutes, int Seconds, double Cost , boolean IsOn, int DSL, int totalSeconds)
  { // Start
    this.Hours = Hours;
    this.Minutes = Minutes;
    this.Seconds = Seconds;
    this.Cost = Cost;
    this.IsOn = IsOn;
    this.DLS = DLS;
    this.totalSeconds = totalSeconds;
  } // End

  public void setTime(int Hours)
  {
    System.out.println(Hours + 1);
  }

  public int convertDaylightSaving(int Hours)
  {
    return Hours;
  }
    public int totalSeconds()
    {
      return totalSeconds + 5000;
    }


  //ToString Method

  public String toString()
  { //Start
    String output;
    output = "When I checked my watch the hour was: " + Hours + "\n" + 
      "When I checked my watch the minute was: " + Minutes + "\n" +
      "When I checked my watch the seconds were: " + Seconds + "\n" +
      "The Cost is: " + Cost + "\n" +
      "Is this the time right now?: " + IsOn + "\n" + 
      "The total seconds right now are: " + totalSeconds;


    return output;

  }
} // End

之后我制作了驱动程序并拥有它return

public class ClockDriver
{ // Start

  public static void main(String[] args)
  { // Officially Start

    Clock Watch = new Clock( 11, 04, 16, 35.99, false, 11, 9945);
    System.out.println(Watch);
}
  } // End
