下面的代码是我今天写的，写的有点乱气八朝。
不多不知道为什么
javac AdminHour.java 可以成功
但是运行就成功不的了
java AdminHour.class 就出现了错误

Exception in thread "main" java.lang.NoClassDefFoundError: AdminHour/class



代码:

import javax.swing.*;

public class AdminHour
{
   public static void main(String[] args)
   {
      Emplogee[] staff = new Emplogee[3];
      
   String   input = JOptionPane.showInputDialog
      ("how much money for A take");
   int k = Integer.parseInt(input);


   input = JOptionPane.showInputDialog
      ("how much money for B take");
   int k1 = Integer.parseInt(input);


   input = JOptionPane.showInputDialog
      ("how much money for C take");
   int k2 = Integer.parseInt(input);


   input = JOptionPane.showInputDialog
      ("How much add ");
   double add = Integer.parseInt(input);


    input = JOptionPane.showInputDialog
      ("how much money for zg take");
   int zgmoney = Integer.parseInt(input);


    input = JOptionPane.showInputDialog
      ("how much money for zg add");
   int zgadd = Integer.parseInt(input);



   staff[0] = new Emplogee("A",k );

   staff[2] = new Emplogee("C",k2);
    Manager boss = new Manager("D",zgmoney);
      boss.setBonus(zgadd);
    staff[3] = boss;

      System.out.println("name=" + e.getName() + "\nOmoney=" + e.getOmoney() + "\nNmoney=" + e.getNmoney());
      }
   }
