Program to search text files in a folder

[kaushalya_uom]

I'm given a project to develop program to search text files in a folder to find matches for a given text and list the containing files. I can't use Java built-in data structures. I have to use my own data structures with algorithms.
I thought of building a data-structure similar to a hash-map to contain the strings found in text files. But i cant think of an algorithm to search.

Thanks in advance for any help!.

All you would need to do is loop thru all the files in the dir, then, in that loop, read thru each file until either you match the text or reach EOF.
What data structures would you need?

First I need to index the strings found in files to optimize the search.

I got a way have a list of txt fils and folders, when we give the rootpath,here it is.

File listOffiles[];
rootFolder=new File(rootPath);
listOffiles=rootFolder.listFiles();//list to store

Here listOffiles will have the list of txt files & folders.
Then try to implement the rest.

Thank you!
I could finish it :-)

But I want to optimize the algorithm.
I searched abooout some text compression algorithms to create codes for words, will it be effective instead of String.compare method?

There is no such thing as a text folder.
Also start a new thread with some code since in this thread there were some suggestions.
If those do not cover you, make your question a little bit more clear
