Java 实现国际象棋 可视化 代码
作者：互联网
要求
modify the previous pogram further by using interface. You can choose either of the followng way:
1 write a Movable interface that includes the abstract Move method
2 write a Movable interface that includes the abstract method to decide if it is a legal movement.
Then modify the indivisual chesspieces not only extends the ChessPiece superclass, but also implements the Movable interface.
一句话，用接口实现国际象棋
代码
哎，这是上学期的代码了，忘了忘了，懒得再看一遍了。
图片资源还有的，需要的私聊我

本次作业发生了较多的错误，总结如下:
- Eclipse不需要较多版本的Java,否则会报错
- Eclipse的非src包不会默认同Package,需要到bilud Path里面设置
- 使用paint()的方法：定义一个打印图片的类，之后用Jframe.add(new 图片类（）)来显示图片。
- 不要害怕陌生的，没有学过的代码，敢于尝试才会有进步。
- Java的官方类比较方便，学会使用其API会使效率更高。
