Write to a txt. file, via user input? (java with netbeans)

:confused: I am working on a read/write program that accesses information from said file..

Reading from it works.
I have been searching for a way to write to a file using using the input from a user.

I have ran into mostly code that is set to auto fill with predefined entries. Any help would be much appreciated.

Any tid bit of code, example, point in the right direction would be awesome..
I know scanner can read from files but i found nothing on it being able to write to files.

Most of what you need to know to learn to write to files can be found here: Lesson: Basic I/O (The Java™ Tutorials > Essential Classes)

Havent had much luck thus far, If there is not already at least 1 entry in the txt file it crashes.

Code:

---

import java.util.Scanner;
import java.io.*;
import java.io.BufferedWriter;

public class ProgramFiles
{

   
    public static void main(String[] args) throws FileNotFoundException, IOException
    {
        File theFile = new File("thisfile.txt");
        Scanner MyFileStalker = new Scanner(theFile);
        String Whatevers = MyFileStalker.next();
        String b = "";
        Scanner Input = new Scanner (System.in);
        BufferedWriter bw;
        bw = new BufferedWriter(new FileWriter("thisfile.txt",true));

        do
        {
            System.out.println("enter a string: ");
            b = Input.next();
            bw.write(b);
           
            System.out.println("value of b"+b);
        }
        while (!(MyFileStalker.next().equals("exit")));
       
       
        do
        {
            System.out.println(MyFileStalker.next()); //using this to track  entries atm.
        }
        while ((MyFileStalker.hasNext()!= false) && (!(MyFileStalker.next().equals("exit"))));
       

    }

}

It looks like you're trying to read out of a file and write to it at the same time. I'd be surprised if the OS will let you do that. What exactly are you trying to have this code do?

For start a loop that asks the user to input string that writes to the txt file.
until they type "exit" to finish that portion of data entry.

The reading portion was an attempt at tracking the file entries....
And will end up being used to spit information back at the user.

Names numbers. So i set up a reference for Searches for those entries.

woot figured it out:D thx muches.
