Reading a TXT file inton an array - java

[Si MPS]

Hi, i've got a textfile named words.txt i want to read into an array, have you any idea how i can do this, because the notes i was given are totally unclear and its driving me insane.

The words are all on seperate lines, no delimiters.

package testbufferedreader;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import javax.swing.*;

class TestBufferedReader extends JFrame{

	private JTextArea j = new JTextArea();
	private Container c;
	public TestBufferedReader() {
		addWindowListener(new WindowAdapter() {
			public void windowClosing(WindowEvent e) {
				dispose();
				System.exit(0);
			}
		});
		// 
		c = getContentPane();
		// add the only control to the content pane
		c.add(j);
	}

    public void readFile() throws IOException {
    	// Open the file
	File inFile     = new File("c:\\limerick.txt");
    	// Create a file stream, wrapping the file
    	FileReader fileReader = new FileReader(inFile);
    	// Create a second wrapper,
    	BufferedReader bufReader  = new BufferedReader(fileReader);
    	// Read in the first line...
    	String s;
    	// Tries to read forever
    	while (true) {
    		s = bufReader.readLine();
    		// a null reference is returned if the end of file 
    	   	// has been reached.  
    	   	if(s == null) throw new EOFException("Hello");
           		// Add the new string to the text area
           		j.append(s);
           		j.append("\n");  // Append a new line to make it look nice
	}
    }


	public static void main(String args[])  {
		System.out.println("Starting TestBufferedReader...");
		TestBufferedReader mainFrame = new TestBufferedReader();
		mainFrame.setSize(400, 400);
		mainFrame.setTitle("TestBufferedReader");
		mainFrame.setVisible(true);
		// Lets add error detection
		try {
		  mainFrame.readFile();
		}
      	catch (FileNotFoundException e) {
			System.out.println("Warning, FileNotFound exception raised"+e);
		}
		catch (IOException e) {
			System.out.println("Warning, I/O exception "+e);
		}
	}
}

This is my code for reading it into a string, to modify this for an array should i put a 'for loop' in and increment the index until ive filled it with the words?

Beaut, got it working, reading into an ArrayList

One other thing, does anyone know an easy way to limit the input of a JTextField, i.e. only put 9 characters in

Another question

  if(evt.getSource()==CreateRandomLetters) {
                                 RandomLetterField = ""; //set initial word to blank
     for (int i=1; i<10; i++ ){ // run code 9 times to generate each letter
        number = Math.random(); // random number 
        numericvalue = (number * 26 + 'a'); //get numeric representation of character
        randomChar = (char) numericvalue;    //convert that number into the character
        RandomLetterField = RandomLetterField + randomChar; //add previous character to word
    }
    RandomLetters.setText(RandomLetterField);

this is my code to generate 9 random characters. anyway, what i wish to know is how can i change it to generate uppercase characters instead?

is there any method i can apply to RandomLetters to switch to all uppercase?
