Java app w/textfield & image problems

Hi there -

I'm trying to develop a regular Java program that has a window with a textfield and an image. When the user types something in the textbox, it is stored and then a new image replaces the old one.

I'm having issues with just getting the text field on:

a snippet of code:

import javax.swing.*;
import javax.swing.border.*;

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

public class TryIO extends JFrame implements ActionListener
{

static JFrame aWindow = new JFrame("This is the Window Title");

public TryIO()
{
Container content = getContentPane();
JPanel panel = JPanel();
JTextField textField = new JTextField("Default input", 20);
panel.add(textField);
content.add(panel, "test");

}


and then when i use JDK to compile i get:

TryIO.java:16: cannot resolve symbol
symbol : method JPanel ()
location: class TryIO
JPanel panel = JPanel();


plus i'm using the:

DataInputStream imagesIn = new DataInputStream(new FileInputStream(myImages));

images[index] = imagesIn.readLine();


and when that compiles I get:

java.io.DataInputStream has been deprecated.

What does that mean and does anyone know how I can get my app to work?

I think the problem is here:



You should create new instance of the JPanel class using it's constructor:



Check out the JPanel class from URL.

Something what is deprecated doesn't exist anymore in new releases of API-packages, although it has been part of the API-package. In this case, DataInputStream's readLine()-method is deprecated since JDK 1.1.

To fix out this problem, replace
