code for searching from file using GUI

---

I'm looking for a code that allows me to search from file , for example, in my program which is shoes shop开发者_高级运维's program . I should design and implement interfaces which have to search data from file TXT. the idea is that when I choose one item like type of shoes the program should display all other times such as color, size and price .

Thanks in advance.

Here's a nice example of a program that does Sorting and Filtering in a JTable. The program's array of sample data could easily be read from a file.
