This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Hi All, I would like get some hint on above. Say, I want to search for a file "test.exe". I want to write a method that returns the exact path of the file if the given file name exist. I can pass the file name and the root directory as the parameters to this method. May be this is a silly question and there is already a class for that and it is one line of coding. :roll:
Basically you could take the String representing your root directory. Use that to create a java.io.File. Using the listFiles method of that File, create an array of Files in that directory. (This array will contain both files and directories represented by java.io.File objects so you may want to create another method to actually get only files or only the directories) You can then iterate through this array, using isFile you can determine if the indexed File is indeed a file and if the name equals the name of the file you are looking for. If you find it you are all set. If you do not find it iterate through the array and recursively send each directory back to this method. Sorry I did not include code. I thought I had something to recursively list files/directories but could not ifnd it. If you still have questions I can try again to find it.

Thanks Timothy, I have used a similar approach. I wanted to know whether there is a short cut way of doing this. I am from C++ background and I found that Java has lot of short cut ways of doing that kind of stuff compared to C. For example, take StringTokeniser class. I would write my own method to do some string manipulaions if I did not know about StringTokeniser which solves the problem within few lines of code.
