    Default Help with making the user input to store in file

    i understand how to print into a file but don't understand how to allow the user to input text so that it stores in the text file.

    import java.io.File;
    import java.io.FileWriter;
    import java.io.IOException;
    import java.io.PrintWriter;
     
    /**
     * Demonstrates how to append text to a file using Java.
     * (Just add a "true" boolean parameter when creating the FileWriter.)
     * Created by Alvin Alexander, [url=http://devdaily.com]devdaily.com | tutorials for java, linux, mac os x, iphone, ipad, uml, quality, testing[/url].
     */
    public class reservation
    {
     
      public static void main(String[] args)
      {
        PrintWriter pw = null;
        try
        {
          // created as a separate variable to emphasize that I'm appending to this file
          boolean append = true;
          pw = new PrintWriter(new FileWriter(new File("output.txt"), append));
          // a print writer gives you many more methods to write with
          pw.println("Hello, World");
        }
        catch (IOException e)
        {
          e.printStackTrace();
          // deal with the exception
        }
        finally
        {
          pw.close();
        }
      }
     
    }

    Default Re: Help with making the user input to store in file

    Is this a duplicated thread? Your other thread - Allow user input to edit text file??
    Please keep all the information in 1 thread rather than starting a new one. I have closed your other thread.

    This is easy to do using the link I provided you - http://www.javaprogrammingforums.com...ner-class.html

        Scanner sc = new Scanner(System.in);
        System.out.println("Add something: ");
        String newText = sc.nextLine();
     
        pw.println(newText);
    Please use [highlight=Java] code [/highlight] tags when posting your code.
