当有一系列人（员工和学生的实例化）时

Question

我有很多人。我已经实例化了子类 员工两次，一个 student 子类。我只想知道为什么我会因为我的平等方法而言是错误的。此代码的大部分来自Core Java卷1基础 ，我正在阅读本书以获取复习，但不知道该如何处理等于方法。是因为它是Person class 。首先，我尝试将其他名称和工资放在人数阵列中的3人身上。我还在陷入虚假。然后我将其切换到同一名称，但仍然有错误。我并不总是了解调试工具，但我认为我的返回声明似乎是问题所在。

package v1ch05.abstractClasses;


public class PersonTest
{
   public static void main(String[] args)
   {
      var people = new Person[3];

      // fill the people array with Student and Employee objects
      people[0] = new Employee("Harry Hacker", 50000, 1989, 10, 1);
      people[1] = new Student("Maria Morris", "computer science");
      people[2] = new Employee("Harry Hacker", 50000, 1989, 10, 1);

      // print out names and descriptions of all Person objects
      for (Person p : people)
         System.out.println(p.getName() + ", " + p.getDescription());
      
      boolean isEmployee = people[0].equals(people[2]);
      System.out.println("Is Employee:" + isEmployee);
   }
   

}
