Getting data from a JTextField

Right now, I am working on a text-based game that (ironically?) is in a GUI. I need to get user input (such as “Turn Left”, “Walk”) from a JTextField. I have had no success so far. The code is as follows.


package com.darkcartgames.textbased.epidemic;

import java.awt.*;
import java.awt.event.*;

import javax.swing.*;

public class Epidemic_TextBased {
	private JFrame frame;
	private JTextArea text;
	private JPanel panel;
	private JButton sendButton;
	private JTextField jtext;

	public static final int WIDTH = 800;
	public static final int HEIGHT = 600;
	public static final String TITLE = "Epidemic TEXT | (C) 2014 DarkCart";
	public static boolean running = false;

	public static void main(String[] args) {
		// It's so ironic that I'm gonna make a text-based game in a JFrame.
		// LOL!
		new Epidemic_TextBased();
	}

	public Epidemic_TextBased() {
		frame = new JFrame();
		frame.setSize(WIDTH, HEIGHT);
		frame.setTitle(TITLE);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setVisible(true);
		frame.setLocationRelativeTo(null);
		text = new JTextArea(10, 20);
		text.setEditable(false);
		frame.getContentPane().add(BorderLayout.CENTER, text);
		text.append("(C) 2014 DarkCart Games \n \n");
		text.append("STORY: \n");
		text.append("Ah, there you are. I've been looking for you. \n");
		text.append("Our village has been hit with a terrible epidemic. \n");
		text.append("We need your help to find 4 bottles of medicine for the town. \n");
		text.append("Will you do it? \n \n");
		text.append("Type OK to help the town \n \n");
		panel = new JPanel();
		jtext = new JTextField(60);
		sendButton = new JButton();
		sendButton.setText("Send");
		panel.add(jtext);
		panel.add(sendButton);
		frame.getContentPane().add(BorderLayout.SOUTH, panel);
		sendButton.addActionListener(new sendButtonListener());
	}

	class sendButtonListener implements ActionListener {

		public void actionPerformed(ActionEvent arg0) {
				String input = jtext.getText();
				text.append(input + "\n \n");
				if (input == "Ok") text.append("tester");
		}

	}
}


Could anyone help me with this?

Thanks,
DarkCart

Never compare Strings with ==

Right, forgot about that.
