Java, need a while loop to reach eof. i.e.while !eof, keep parsing

Question

I currently have a working parser. It parses a file once(not what I want it to do) and then outputs parsed data into a file. I need it to keep parsing and appending to the s

Instead of looping until an EOFException is thrown, you could take a much cleaner approach, and use available().

DataInputStream dis = new DataInputStream(new FileInputStream(inFile));
while (dis.available() > 0) {
    // read and use data
}

Alternatively, if you choose to take the EOF approach, you would want to set a boolean upon the exception being caught, and use that boolean in your loop, but I do not recommend it:

DataInputStream dis = new DataInputStream(new FileInputStream(inFile));
boolean eof = false;
while (!eof) {
    try {
        // read and use data
    } catch (EOFException e) {
        eof = true;
    }
}
