为什么我的 2D Array Maze 不打印生成的内容？

Question

我的目标是生成一个由 Cell 对象的 2D 数组组成的迷宫。下面是单元格和迷宫的代码。使用调试器我可以看到布尔值正在改变值，并且生成按预期进行，但是当它打印出来时，没有路径。所有的墙都还在原地，我似乎无法弄清楚断开的位置，如果有的话？

这是 Cell 类：

public class Cell {

    //coordinates

    private int x;

    private int y;

    //cell status

    private boolean visited;

    //cell walls status

    private boolean northWall;

    private boolean southWall;

    private boolean eastWall;

    private boolean westWall;

    public Cell(int x, int y) {

        this.x = x;

        this.y = y;

        visited =  false;

        northWall= true;

        southWall= true;

        eastWall = true;

        westWall = true;

    }

    public int getX() {

        return x;

    }

    public int getY() {

        return y;

    }

    public boolean isVisited() {

        return visited;

    }

    public void setVisited(boolean visited) {

        this.visited = visited;

    }

    public boolean isNorthWall() {

        return northWall;

    }

    public void setNorthWall(boolean northWall) {

        this.northWall = northWall;

    }

    public boolean isSouthWall() {

        return southWall;

    }

    public void setSouthWall(boolean southWall) {

        this.southWall = southWall;

    }

    public boolean isEastWall() {

        return eastWall;

    }

    public void setEastWall(boolean eastWall) {

        this.eastWall = eastWall;

    }

    public boolean isWestWall() {

        return westWall;

    }

    public void setWestWall(boolean westWall) {

        this.westWall = westWall;

    }

Answer 1

你不是在打印你的迷宫。在该printMaze()方法中，您正确地循环了迷宫，但不是打印出迷宫单元格，而是在每次迭代时创建一个新的（空白）单元格。public void printMaze() {&nbsp; &nbsp; for (int i = 0; i < height; i++) {&nbsp; &nbsp; &nbsp; &nbsp; /* ... */&nbsp; &nbsp; &nbsp; &nbsp; for (int j = 0; j < width; j++) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Cell current = new Cell(i, j); // <- HERE&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; /* ... */&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; /* ... */&nbsp; &nbsp; }&nbsp; &nbsp; /* ... */}该行应该是：Cell current = maze[i][j];

Answer 2

而不是：Cell current = new Cell(i, j);尝试：细胞电流 = 迷宫 [i,j];
