Asking Console

[righi]

Hi all, I hope someone can help me because I'm gonna get crazy with this problem...


This is the idea of what the program must do: reading a txt file where every line there is a String and ask the user if it's a person name or no.

So the problem is:

I have a class that read a txt file; then every text line the program ask the user (via eclipse console) to say if it's a person name or not (y/n).

For this I have simply done : while ((str = text.readLine()) != null) and then I ask the user with the normal scanner(system.in) to write y or n and then I check the scanner input : if y I save str in an ArrayList...if not the while loop and a new str is created and a new question is done...

This is the idea for the console program and it work...now I want to make this work out of eclipse...using a simple GUI console

Now I have made a new class called AskConsole() that create a simple Window with a JtextArea and a JtextFiled to use as a console... in the textArea the program must print the line of text that is currently read;
then the program mus stop, wait for the user to write in the text field y or n (then enter to say ok I've written the answer) and now the program can continue the while loop as before...

I hope that the problem is clear enough...if not ask me more details...

thanks all

Hi all...I post here my solution...after I few try I got the answer...

 public class Program {
public static void main(String[] args) {
 
	ReadTxt reader = new ReadTxt();
 
}
}
 
class ReadTxt{
	private Scanner scan= new Scanner(System.in);
 
	public ReadTxt(){
		Thread t= new Thread("askT");
 
		GuiConsole guiCon= new GuiConsole(t);
		char response=' ';
		File f = new File("C:/name.txt");
		try {
			FileInputStream fis = new FileInputStream(f);
			BufferedReader buff= new BufferedReader(new InputStreamReader(fis));
			String str="";
			while((str=buff.readLine())!=null){
				guiCon.printText(str + " : is a name?  (y / n)");
 
//				response= scan.next().charAt(0);
				synchronized (t) {
					try {
						t.wait();
					} catch (InterruptedException e) {
						throw new RuntimeException(e);
					}
				}
				response=guiCon.getResp().charAt(0);
 
				switch(response){
				case'y': guiCon.printText("Name !");
				break;
				default: guiCon.printText("no...");
				}
 
			}
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
 
	}
}
 
 
 
public class GuiConsole {
 
	private JFrame window;
	private JScrollPane scroll;
	private JTextArea console;
	private JTextField answerField;
	private JPanel textPanel;
	private String resp = "";
 
	private Thread wT = null;
 
	public GuiConsole(Thread waitingT) {
		window = new JFrame("GUI CONSOLE");
		wT=waitingT;
		try {
			UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
		} catch (Exception e) {
			System.out.println("Error setting native LookAndFeel: ");
		}
 
		console = new JTextArea("Started:\n**********");
		console.setLineWrap(true);
		scroll = new JScrollPane(console);
		scroll.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
		scroll.setWheelScrollingEnabled(true);
		answerField = new JTextField();
		textPanel = new JPanel();
 
		GridBagLayout layout = new GridBagLayout();
		GridBagConstraints lim = new GridBagConstraints();
		textPanel.setLayout(layout);
		lim.insets.top = 10;
		lim.insets.bottom = 5;
		lim.insets.left = 10;
		lim.insets.right = 10;
		lim.fill = GridBagConstraints.BOTH;
 
		lim.gridx = 0;
		lim.gridy = 0;
		lim.weightx = 1;
		lim.weighty = 1;
		layout.setConstraints(scroll, lim);
		textPanel.add(scroll);
		lim.insets.bottom = 30;
		lim.gridx = 0;
		lim.gridy = 1;
		lim.weightx = 1;
		lim.weighty = 0;
		lim.fill = GridBagConstraints.HORIZONTAL;
		layout.setConstraints(answerField, lim);
		textPanel.add(answerField);
 
		answerField.addKeyListener(keyLis);
 
		window.add(textPanel);
 
		window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
		window.setSize(new Dimension(500, 500));
		window.setVisible(true);
 
	}
 
	private KeyListener keyLis = new KeyListener() {
 
		@Override
		public void keyTyped(KeyEvent t) {
 
		}
 
		@Override
		public void keyReleased(KeyEvent r) {
 
		}
 
		@Override
		public void keyPressed(KeyEvent p) {
			if (p.getKeyCode() == KeyEvent.VK_ENTER) {
				console.append("\n" + answerField.getText());
				resp = answerField.getText();
				answerField.setText("");
				synchronized (wT) {
					wT.notify();
 
				}
			}
		};
 
	};
 
	public void printText(String m) {
		console.append("\n" + m);
	}
 
	public String getResp() {
		return resp;
	}
}

If you aren't using it as a homework assignment, I have made a class that is very similar to this that acts similarly to console except more user-friendly, for this very purpose. Feel free to check it out at Windows 7 Console
