推荐答案

转到 http://docs.oracle.com/javase/tutorial/index.html [ ^ ]并完成教程标题为覆盖基础知识的路径。这应该可以帮助你开始。

Go to http://docs.oracle.com/javase/tutorial/index.html[^] and work through the tutorials in the section headed Trails Covering the Basics. That should help you get started.

import java.awt.List;
import java.util.ArrayList;
 
public interface Person{ // make it a public. Is an interface demanded?
  public String getName();
}
 

public class Course{ // also public 
  private ArrayList students = new ArrayList(); // this is private!

  public addStudent(student: Student){

  }

  public void getNumberOfStudents(){ // public method

  }
}

visibillity似乎不太清楚。请阅读该问题。



是否需要界面？这个家庭作业通常没有接口。

对象上缺少成员变量老师 course 。



控制类（主方法的那个）在哪里？

visibillity seems not to be clear to you. Please read on that issue.

Is the interface demanded? This homework normally comes without interfaces.
The member variable teacher is missing on the object course.

Where is the controlling class (the one with the main method) ?
