如何编写一个记事本程序

Question

    因为我长期看小说，而且是用电脑看，感觉有时候这个屏幕太亮了，所以想开发一个可以调节背景色，字体颜色，以及滚动条，菜单条颜色的记事本程序，但因为技术所限，写不出来，所以一直都是编写个html文件，设置背景色，字体色，但是滚动条的颜色还是没变。跪求各位大大给个java 编写的  能够调节背景色，字体色，滚动条，菜单条颜色 的记事本程序的代码

Answer 1

swing嘛。IO流嘛嘛
其实你要求的记事本程序挺简单的。
不过你看长期看小说，，那

Answer 2

Java写这玩意很不靠谱，都是VC或者Delphi写。

Answer 3

Swing+IO，很简单的…上网找找教程…
