Writing data to a text file

 

Writing data to a text file, Need help possibly writing a loop in a text file

Here is my code for this text file:

CODE

import java.util.Scanner;  // Needed for Scanner class
import java.io.*;          // Needed for file classes

System.out.println("Please enter the name of the file.");
filename = keyboard.nextLine;

Filewriter fwriter = new Filewriter(student.txt);
PrintWriter outputFile = new Printwriter(fwriter);
outputFile.open();

//Now that we're open, we can do what we want, right?



And...that's where my excitement ended. How do I create a loop that will display the contents of the file with each line numbe followed by a colon? Like...print out:

1:

...wait for the user to enter data, and then when they press enter, show a number two? I am just assuming this will be done with a loop...

Any help is appreciated, thanks in advance!

Something like this should work:

int linenumber = 0;
do
-->print to console: ++linenumber + ": "
-->get input
-->print to file: linenumber + ": " + user input
while(continue condition)

Where at the end of while loop you ask the user if there is more input, if there is continue the loop.

And

Filewriter fwriter = new Filewriter("student.txt");

student.txt between "" or you mean

Filewriter fwriter = new Filewriter(filename);
