自学JAVA不久，第一次自己编小程序。在家摸索了三天才完成。

* 对于如何选择合适类还没有经验，这里直接在JFrame上设计paint()方法将所有内容绘制。没有掌握面向对象编程还- -！

* 建模上借鉴了小时候玩的那中手柄游戏，将主面板划分为12*20的小格；后来为了设计碰撞，又改为14*21，绘制部分仍为12*20。（两侧与底部为边界）

* 这些格子的信息用一个二维数组存储，数组中每个元素用0，1来表示是否被绘制成黑色。paint（）方法中将值为1的格子绘制成黑色，0的仍为白色。边界除外）

-Soon, the first self-study JAVA own small programs. At home the three genius.

* how to choose appropriate class haven t experience, here in JFrame directly on the paint () method to design all content. No master object-oriented programming still--!

On a childhood* modeling in that play the game, will handle panel is divided into 12* 20 small lattice, Later in order to design, and 14* collision, drawing part for 21 December 20. And for the sides (bottom border)

The information in the grid**** a 2d array stores, each element in the array is whether to use 0,1 drawn into black. Paint () method of value is 1, 0 draw black grid for white still. Boundary except)
