java - 提示找不到或加载主类时，如何使该程序运行？

我对Java非常陌生，并且不断收到此错误，我无法弄清楚。


  错误：找不到或加载主类
  restaurantclient.RestaurantClient
  Java结果：1


这是在Netbeans上，我确定我做对了所有事情。这是我为Java课编写的作业，非常感谢您的帮助。我已经在这个问题上工作了几天了。

import java.text.DecimalFormat;

public class RestaurantClient {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        Restaurant r1;
        Restaurant r2;
        r1 = new Restaurant("PizzaHut", 152, (float) 4.95); //instantiating
        r2 = new Restaurant("Dominos", 10, (float) 3.657);
        System.out.print(r1.toString());
        System.out.print(r2.toString());
        r2.setPeopleServed(r1.getPeopleServed());
        r2.setAveragePrice(r1.getAverageMeal());
        if (r1.equals(r2)) //checking if equal
            System.out.println("\nThe two objects are the same");
        else
            System.out.println("\nThe two objects are NOT the same");
        r2.setName(r1.getName());
        if (r1.equals(r2)) //checking if equal
            System.out.println("\nThe two objects are the same");
        else
            System.out.println("\nThe two objects are NOT the same");
        DecimalFormat pricePattern = new DecimalFormat("$###,###,000.00");
        System.out.println("Tax paid per year: " + pricePattern.format(r1.averageTaxes()));

    }

}

最佳答案

系统正在寻找主类restaurantclient.RestaurantClient，因此在包RestaurantClient中有一个类restaurantClient，但是您的类RestaurantClient似乎在默认软件包中。
