      我将上面源代码编译后,打成可执行的Jar包,运行效果如下:

  我这运行一直没问题,用不同的机子也没问题,你出错,通常可能是我的代码贴到网页时发生的改变,例如英文字符变成中文字符等,另外网页可能加了特殊符号,我想这个网友应该会根据错误提示自己改吧。  回复  更多评论

这个记事本还有一个小Bug,就是关闭记事本时,在对话框选择撤消后,本来应该不退出程序的,大家可以自己想想方法解决这个问题。  回复  更多评论

@小丫蛋
修改一个地方就可以了,把下面的这句
getContentPane().add(scrollPane, " Center " );

改成:this.add(scrollPane); 就可以了.  回复  更多评论

编译时提示:
类 NotePad 是公共的,应在名为 NotePad.java 的文件中声明
这是什么情况?  回复  更多评论
