如何用JAVA编写一个图片的拼图游戏
说说思路:
1 本身他不是一个完整的图片，应该被切分成数组，该数组为拼图成功的标准
2 将该数组复制，然后打散元素的顺序
3 初始化一个二维数组方格矩阵
4 允许用户通过鼠标事件将 备选图案中的某个元素放置到二维数组方格矩阵中，并记载其顺序
5 直到所有的方格被填满，与答案数组的元素顺序比较，给出结果
以上是实现拼图的关键思路，其他情况还要考虑，如允许从方格中撤出图像或者与其他图像调整位置，仅代表个人不成熟的想法，希望对你能有所帮助，祝你好运！

java拼图游戏不成功为什么
从代码和错误提示来看
button 对象只有声明, 并没有赋值,默认是null .用一个null对象去调用方法,那么就会抛出异常.没有进行异常处理,程序就会崩溃
button.addActionListener(new ImgButtonAction());// 出错...因为button为null
解决办法: button对象先赋值(不能为null)再使用
建议你写代码,添加必要的注释,对每个方法的说明, 以及对每个比较难一眼看懂的算法进行说明.,会比较好.
以前也写过一个拼图,比较简单.思路跟你可能差不多:
1:用按钮去显示图片的一部分.并且每个按钮都有个value属性,从1,2,3,....9,0
(value为0按钮在最后面,并不显示图片) .想要胜利,就需要图片按钮的value属性能满足下面的二维数组
int[][] win = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 0 } };
2: 点击图片按钮,判断是否可以交换位置,如果旁边是value为0的按钮,那么可以交换位置,每次交换后,记得判断是否胜利
3: 打乱的图片按钮,不一定能求解, 如果不能求解,那么重新打乱
效果图大概是
