2D数组和JButton [英] 2D array AND JButton

问题描述

现在我需要编写一个8谜题的游戏，看起来[像这样]

Now I need to write a 8-puzzle game, which looks [like this]

讲师要求我们编写三个不同的类，分别是Piece.java，EightPuzzle.java和EightPuzzlePanel.java.如你看到的，Piece.java在这八个拼图板上代表每个单独的片断，例如"1"，"2"；EightPuzzle.java代表游戏板，可容纳这9个部件/按钮.ThreePuzzlePanel.java是GUI的东西.

The instructor asked us to write three different classes, which are Piece.java, EightPuzzle.java, and EightPuzzlePanel.java. As you can see, Piece.java represents each individual piece like "1", "2" in this eight puzzle board; EightPuzzle.java represents the the game board to hold these 9 pieces/buttons. EightPuzzlePanel.java is the GUI stuff.

所以我的问题是，因为我们需要创建一个Piece [] [] piece = new Piece [] [](一个2D数组)，并且还需要将这些块布置在板上.我以为我可以创建9个JButton，并将2D数组与9个JButton链接在一起(或者有更好的方法对2D数组进行排序)，但是我不知道该怎么做.

So my question is, since we need to create a Piece[][] piece = new Piece[][], a 2D array, and we also need to arrange these piece on the board. I thought I could create 9 JButtons and put the 2D array in link with the 9 JButtons (or there have a better way to sort the 2D-array), but I don't know how to do that.

此外，还需要同时通过鼠标和键盘来控制按钮.这对我来说是另一个挑战.

Also the buttons need to be controlled by both mouse and keyboard. This is another challenge for me.

推荐答案

由于这是家庭作业，因此我不会详细介绍，但这是我的处理方式:

Since this is homework I will not go into much detail, but this is how I would go about it:

1. 使 Piece 扩展 JButton 类. Piece 对象可以显示文本以及要渲染的图像的位置.您应该可以在网上找到很多有关如何将图像添加到 JButton 的示例.
2. 使 EightPuzzle 扩展 JPanel 类，并使用

1. Make Piece extends the JButton class. The Piece object takes the text to display and also the location of the image you would like it to render. You should be able to find plenty of examples online on how to add an image to a JButton.
2. Make EightPuzzle extend the JPanel class and also use the Grid Layout to render the Pieces neatly in a grid. This class takes on a 2D array of Piece objects which it will then render.
3. Make EightPuzzlePanel also extend the JPanel class. This class takes in another JPanel (EightPuzzle) and appends any other buttons you might need.
4. Finally create a Main class which extends JFrame and then I append the EightPuzzlePanel to it (which should in turn contain the other panel with the other buttons).
