读一个开源项目JJJ的源代码

自从我开始学习java,看了<thinking in java>的前6章,发现那本书不适合没有java基础的人学习.我买了一本<java core:基础知识>在读,我发现那本书写的不错,也很适合我门这种菜鸟来读.读起来那本书就象在吃肉家膜.

我感觉学习java技术的捷径应该是从实践入手,看别人的原代码一定可以对学习的知识有到认识和提高的过程,一定可以加快自己学习的过程,所以我找了一个开源的软件下来看看他的原代码,我下的这个项目叫做J,是一个多文本的文本编辑器,适合程序员使用,因为他可以分析原代码的类,并列出表来.还可以语法高亮显示.其实感觉挺不错的.我看了他的原代码,写的不错,格式很好看,就是注释的太少了,我感觉是不是开源的软件代码应该对写点注释才会更好呀.下面我给出我今天看的那个Main.java的代码,其实没有几行的,不过感觉自己的收获不小呀!!!
