16、fillOval(xpos, ypos, 30, 30);if(state=4)g.fillOval(xpos, ypos, 30, 30);遇到的问题和解决方法在编写程序时：我遇到了图片加载不到applet小程序里的情况，首先我查看了我图片存放的路径，看是否和我编写的java程序在同一目录下，然后再重新加载。在编写Thread的时候实现Runnable接口和继承Thread有区别，一个直接可以使用，另一个得先声明时Thread对象，再实现接口。心得体会在编写的同时要细心认真，布局好每一个compotent,使画面更美观 本科实验报告课程名称： Java程序设计 实验项目：实验四 网络、数据库
