Java - 创建类的实例，然后在其他地方使用它

I have three classes that need to communicate with eachother: a MainClass, which will be the main running line; a Maze class, which will contain MazeObjects; and a MazeObject class, which will populate the maze. In my MainClass, I am creating a Maze object Maze maze = new Maze() , which will populate it with walls in its constructor. I am then trying to fill the maze with MazeObjects, from the same MainClass, by calling the MazeObject class, which has methods to do so. So my question is, how am I supposed to give the MazeObject class a copy of the maze so that it can populate it with maze objects?

我有三个需要与彼此通信的类:一个MainClass,它将是主要的运行线;一个Maze类,它将包含MazeObjects;和一个MazeObject类,它将填充迷宫。在我的MainClass中,我正在创建一个Maze对象Maze maze = new Maze(),它将在其构造函数中填充墙。然后我尝试通过调用MazeObject类来填充迷宫与MazeObjects,来自同一个MainClass,MazeObject类具有这样做的方法。所以我的问题是,我怎么能给MazeObject类一个迷宫的副本,以便它可以用迷宫对象填充它?

public class MainClass {
    public static void main(String[] args){
        Maze maze = new Maze(); //This creates the new maze object
        MazeObject mazeObject = new MazeObject() //Populates the maze with tons of                                      different types of maze objects

How am I supposed to implement the MazeObject class so that it will be able to take the newly created maze in order to populate the maze?

我该如何实现MazeObject类,以便它能够采用新创建的迷宫来填充迷宫?

To do that, you can make a constructor that takes the maze like this:

要做到这一点,你可以创建一个像这样迷宫的构造函数:

public static void main(String[] args){
    Maze maze = new Maze();
    MazeObject mazeObject = new MazeObject(maze);
}

Maze object will have a reference to Maze like this

迷宫对象会像这样引用迷宫

class MazeObject {
    private Maze maze;
    public MazeObject(Maze maze) {
        this.maze = maze;
    }
}
