how do you open / read / write to a file in java?

Not completely sure, but wouldn't it be somewhat the same as inputting it to a variable? I've been juggling C++ and java around for school, so not exactly sure of the syntax but something using an input operator '>'?

inputStream?

I Know i know!!

ok here is the code for writing to a file:

FileOutputStream fileHandle;
PrintWriter outputFile;

fileHandle = new FileOutputStream ("TopTen.txt");
outputFile = new PrintWriter(fileHandle);

and then after you declare this you can use
outputFile.print("whatever you want");
-OR-
outputFile.println("----");

if you just put in the name of the file like I did, it will go to the directory where your .java file is! if you want to go to another directory, you put the full path in there, ex. ("C:\\file.txt") you need 2 slashes because java takes the \ as a special character so \\ would be considered 1 \!

Reading from file:

FileReader File1;//creates a file input object
BufferedReader fileReader;//creates a buffered reader object
File1 = new FileReader("TopTen.txt");
fileReader = new BufferedReader (File1);

and then you use fileReader.readLine();
ex. temp = fileReader.readLine();

that takes input as a String, so you would have to use parseInt to go to Integer and so on!

thanx
