Question

My file program works fine. It creates a txt file with the contents I submitted. But, why does my console display ‘true’ infinitely?

        Scanner input = new Scanner(System.in);
        System.out.println("What would you like the file to be called?");
        String output = input.nextLine();

        if (!output.contains(".txt")) {
            output += ".txt";
        }

        PrintWriter out = new PrintWriter(output);
        System.out.println("What would you like to print to the file? ");
        String fileContents = input.nextLine();
        out.print(fileContents);
        out.close();

        Scanner fromFile = new Scanner(new File(output));

        System.out.println("The File " + output + " contains: ");

        while (fromFile.hasNextLine()) {
            System.out.println(fromFile.hasNextLine());
        }

        System.out.println("Finished reading and writing from file.. ");
        input.close();
        fromFile.close();

}

Answer 1

You are not actually retrieving the next line

while (fromFile.hasNextLine()) {
    System.out.println(fromFile.hasNextLine());
}

Your print statement is simply re-checking that it has a newline. I think what you meant to do was

System.out.println(fromFile.nextLine());

By calling nextLine() you are telling Scanner that you want to consume all the characters up to the next '\n' (newline) character. See the Scanner class for more information.
