I have this kind of structure that I want to both read and write to a file, and I want to do it the fastest way possible. class Map { String name; int tiles[][]; } What is the best way to do this? I'm a C++ programmer mostly, and I don't know the best way to do this in Java. It seems like it should be really simple, but I don't kn...
How can I request the user to input the filename that my program needs to read from and have it output the name with ".out" instead? Example: char fileName[256]; cout << "What is the file name that should be processed?"; cin >> fileName; inFile.open(fileName); outFile.open(fileName); But I need it to save the file as a filename.out ...
I am curious as to how I would go about reading the input from a text file with no set structure (Such as notes or a small report) word by word. The text for example might be structured like this: "06/05/1992 Today is a good day; The worm has turned and the battle was won." I was thinking maybe getting the line using getline, and then ...
I have been recently involved in handling the console logs for a server and I was wondering, out of curiosity, that is there a performance issue in writing to a large file as compared to small ones. For instance is it a good idea to keep the log file size small instead of letting them grow bulky, but I was not able to argue much in favo...

I'm trying to put together a function that receives a file path, identifies what it is, sets the appropriate headers, and serves it just like Apache would. The reason I am doing this is because I need to use PHP to process some information about the request before serving the file. Speed is critical virtual() isn't an option Must wor...

Hi everyone, I have a configuration file that has variables and value separate by spaces. I want to take the value (in the second column) of certain matches and inline edit the file, dividing this match by 2. I also would like to preserve spacing and use a ceiling function on the value. For example, the file: To recap, using an actu...
Hello, once again I ask for help. I haven't coded anything for sometime! Now I have a text file filled with random gibberish. I already have a basic idea on how I will count the number of occurrences per word. What really stumps me is how I will determine what line the word is in. Gut instinct tells me to look for the newline character...

I'm writing code that check files path calculate hash (SHA1) and copy them.

It's been a while since I've done Java I/O, and I'm not aware of the latest "right" ways to work with Zip and GZip files. I don't necessarily need a full working demo - I'm primarily looking for the right interfaces and methods to be using. Yes, I could look up any random tutorial on this, but performance is an issue (these files can get...
I know this is likely to be an open-ended kind of question, but I'll take the best-regarded answers and consolidate them here for reference. I'm working on a set of tools to read and write Mobipocket files (a.k.a. Kindle eBooks) using C#, and am running into a design question when it comes to writing new files. The underlying file form...
I've been googling around and reading through my book and trying to write out code to read through a text file and process words out of it, one by one, so i can put them in alphabetical order and keep a count of how many words where used and much a word was used.
