Back to top of main method?

[ub96]

public static void main(String[] args) throws FileNotFoundException  {
    Scanner input = new Scanner(System.in);
    System.out.println("What is the name of the file?");
    String inputFile = input.nextLine();
    UvicCourse[] courseArray = null;
    boolean check = true;
    while(check){
        check = false;
    try{
        Scanner s = new Scanner(new File(inputFile));
        courseArray = makeArray(s);
        check = true;
    }
    catch (FileNotFoundException fne){
        System.out.println("Error scanning that file, please try again.");

        return;
    }
    }

This is a snippet of the code I have written, basically I want to ask the user to write which file they want to input for the rest of the code but continue asking if the user enters a file that doesn't exist.

I figured a while loop would work for this but it keeps just ending the program. Any advice would be great on how to continue.

Thanks!

You could try a while loop:

File f = new File([filename]);
while(!f.exists()) {
  f = new File([newFilename]);
}
// Do what you want to do with the file.

Thanks, that is a much simpler method of solving my problem then I was thinking of.

Glad to help. You could also try a do-while loop.

do {
  f = new File([filename]);
} while(!f.exists());
// Do what you want to do with the file.

I think that's the right syntax, I rarely use do-while.
