JAVA实现走迷宫图小程序.docx

CanvasPalyBL 类：CanvasPalyBL 类继承了Canvas组件，Canvas 组件表示屏幕上一个空白矩形区域，应用程序可以在该区域内绘图，或者可以从该区域捕获用户的输入事件。 应用程序必须为 Canvas 类创建子类，以获得有用的功能（如创建自定义组件）。必须重写 paint 方法，以便在 canvas 上执行自定义图形。import java.awt.Canvas;import java.awt.Color;import java.awt.Graphics;import javax.swing.JOptionPane;public class CanvasPalyBL extends Canvasfinal int unitSize =10;
