Question

txt文本文档内容提取的Java源码

例如文本包含以下内容：
===== RRC State Machine Simulation =====
DCH (Active):,363.93 ,S,88.62%
FACH (Standby):,24.71 ,S,6.02%

===== Energy Efficiency Simulation =====
DCH (Active):,473.11 ,J
FACH (Standby):,7.41 ,J
现在想直接提取Energy Efficiency Simulation下的DCH (Active):值为多少（J），做一个GUI界面，效果为将一个txt文档拖放进窗体后，能直接显示相应的值，窗体界面类似下图，

求高手解答！

Answer 2

拖进窗口？是类似html文件直接拖到ie然后运行的那种？

追问

是的，即 JFrame窗体实现DropTargetListener接口
public class TestResultView extends JFrame implements ActionListener,DropTargetListener{...}.
如果麻烦，就不用做窗体界面，直接能在控制台输出结果也行
