我正在完成我的Java编程教科书中的练习作业，遇到了常见的“错误：找不到符号”.“我必须创建一个引用同一目录中另一个类得应用程序，但编译器找不到该类.
下面是www.example.com的代码SpaService.java:

package com.spaservice;

public class SpaService {
    private String serviceDescription;
    private double price;

    public void setServiceDescription(String service){
        serviceDescription = service;
    }
    public void setPrice(double servicePrice){
        price = servicePrice;
    }

    public String getServiceDescription(){
        return serviceDescription;
    }
    public double getPrice(){
        return price;
    }
}

这是我的www.example.com代码CreateSpaServices.java

package com.spaservice;
import java.util.Scanner;

public class CreateSpaServices {

    public static void main(String args[]) {
        String service;
        double price;

        SpaService firstService = new SpaService();
        SpaService secondService = new SpaService();
        Scanner keyboard = new Scanner(System.in);

        System.out.print("Enter service >> ");
        service = keyboard.nextLine();
        System.out.print("Enter price >> ");
        price = keyboard.nextDouble();

        firstService.setServiceDescription(service);
        firstService.setPrice(price);

        keyboard.nextLine();
        System.out.print("Enter service >> ");
        service = keyboard.nextLine();
        System.out.print("Enter price >> ");
        price = keyboard.nextDouble();

        secondService.setServiceDescription(service);
        secondService.setPrice(price);

        System.out.println("First service details:");
        System.out.println(firstService.getServiceDescription() +
        " $" + firstService.getPrice());
        System.out.println("Second service details:");
        System.out.println(secondService.getServiceDescription() +
        " $" + secondService.getPrice());
    }
}

这是一个相当简单的程序，但是由于某种原因CreateSpaServices.java找不到SpaService.class。

我正在使用Netbeans 12. 3来编写这段代码，它使用IDE编译得很好。我使用的是Windows 10。
根据研究，我在Stack Overflow上也发现了类似的问题。我试着从src文件夹、java文件夹和com文件夹运行该命令，结果都是类似的。我怀疑这个问题可能与软件包有关，但我对Java的了解还不足以自己解决问题。我希望我能从社区获得一些帮助。
让我知道你的想法。任何帮助将不胜感激。
