求教 从文件mulu.txt中读取内容建树的例子，万分感谢！

[harbor1981]

mulu.txt内容假设为福建，广东，浙江等，要建一个树，树目录为福建，广东，浙江

请各位大哥大姐提供一个完整的代码，谢先了！

我写过一个读FtpRush做的Ftp目录列表文件，然后用JTree显示出来的程序，要是觉得可以参考一下的话，留下email

[harbor1981]

感谢jFresH_MaN(The answer is ......) 指点，小弟刚学java不久，请问用XML又如何实现呢？谢谢！我的邮箱 [e-mail] 同时谢谢楼上的

[cchaha]

我也不懂,烦请知道的发到我的邮箱:[e-mail]
先谢谢了

[jFresH_MaN]

晕，怎么不用xml

[harbor1981]

难道就没有人肯帮我这个忙吗？5555555555555555555555

[jFresH_MaN]

我的意思是你把你的目录内容应该写在一个xml里面
因为xml本来就是一个树型结构的
然后使用dom,jdom或者sax来读取数据都是很简单的

[jFresH_MaN]

当然如果你是初学者那就直接读txt也行
FileInputStream reader=new FileInputStream("mulu.txt");
具体的你查一下api啊，这个还是很基础的问题

谢谢大家，今结贴！

感谢 bj_sztj给我的例子，但是我感觉还是难了一点

因为里面有很多涉及到import org.w3c.dom.*;和XML方面的

东西对我来说都是新知识，希望 bj_sztj能够再给一个比较简单的

例子，我们好观摩观摩，谢谢了
