Tab Search

Question

Im working on a program where a user inputs the following when prompted: an input file name, and a new output filename. The program is supposed to search through the first file name and find all tab characters and replace them with spaces and place the final product in the second file. This program is supposed to be robust, such that if the user inputs a file that doesnt exist they will recieve an error message and re-enter the filename without the program crashing. I am having problems with recieving the user input. I have been using System.out.println() to display output but I cannot find how to recieve any input. I havent had very much experience writting to new files so I am having trouble writing to the output file name. FileOutputStream?? I also am having problems with the program being robust and not crashing when the user inputs something wrong. FileNotFoundException?? Thanks for whoever can help.

Answer 1

I personally ALWAYS make use of a GUI of some sort, the command line just bothers me for some reason....
Anyway, to output to files use this:
try {
DataOutputStream outFile = new DataOutputStream(
new FileOutputStream("File Name.***");
outFile.writeBytes("Some Data");
}catch(IOException e){*put your FileNotFound Code here*/}
NOTE: This will overwrite existing files
To replace tabs:
String s1="YourData";
s1=""+s1.replace('\t',' ');
