java - 在线编译器不会运行多个类

Question

我正在使用在线编译器“onlinegdp”来运行java，但我无法在编程中使用多个文件。完全相同的代码在 Eclipse 上工作，所以我不确定问题出在哪里。

我对java了解不够，无法尝试除Object myObject = newObject();之外的任何东西。 。所以任何事情都会有帮助。

这就是我的 worker 类(Class)的内容

public class Worker
{
  private int hours;
  private double rate;
public Worker ()
{
  hours = 999;
  rate = 999;
}
public Worker (int nHours, double nRate)
{
  hours = nHours;
  rate = nRate;
}
public int getHours ()
{
  return hours;
}
public void setHours (int nHours)
{
  hours = nHours;
}
public double getRate ()
{
  return rate;
}
public void setRate (double nRate)
{
  rate = nRate;
}
public double paycheck ()
{
  return rate * hours;
}
public void raiseRate (double raiseRate)
{
  rate = raiseRate + rate;
}

}

这是主类

public class Main
{

public static void main (String[]args)
{
  Worker bob = new Worker ();
  System.out.println (bob.getHours ());
  System.out.println (bob.getRate ());
  bob.setHours (9);
  bob.setRate (7.9);
  System.out.println (bob.getHours ());
  System.out.println (bob.getRate ());
  System.out.println (bob.payCheck ());
  System.out.println (bob.raiseRate ());
}
}

我收到此错误
Main.java:14: 错误:找不到符号
Worker bob = new Worker();
^
符号:Worker类
位置:Main 类

Answer 1

我不知道 onlinegdp - 在线编译器如何保存另一个类文件并引用它。如果它们有功能，那么您可以尝试将它们添加到包中并使用包导入该文件。

It's pain to see the folder/project structure on most of the online compiler. They are meant to run small snippet & not to run the whole project.

下面是您可以在 onlinegdp 上运行的代码片段，而无需创建不同的文件。

public class Main
{
  public static void main (String[]args)
  {
    Worker bob = new Worker ();
      System.out.println (bob.getHours ());
  }

  static public class Worker
  {
    private int hours;
    private double rate;
    public Worker ()
    {
      hours = 999;
      rate = 999;
    }
    public Worker (int nHours, double nRate)
    {
      hours = nHours;
      rate = nRate;
    }
    public int getHours ()
    {
      return hours;
    }
    public void setHours (int nHours)
    {
      hours = nHours;
    }
    public double getRate ()
    {
      return rate;
    }
    public void setRate (double nRate)
    {
      rate = nRate;
    }
    public double paycheck ()
    {
      return rate * hours;
    }
    public void raise (double raise)
    {
      rate = raise + rate;
    }

  }

}
