Assignment #6

Due Date: Fri, Apr 22

Objective

This assignment will help you gain practice with basic Swing components and basic event handling.

Write an application that plays "guess the number" as follows:

Your application chooses the number to be guessed by selecting an integer at random in the range 1-1000. The application then displays the following in a label:
```
     I have a number between 1 and 1000. Can you guess my number?
     Please enter your first guess.
```
A JTextField should be used to input the guess. (Use an ActionEvent to activate an event on the text field)
As each guess is input, the background color should change to either red or blue. Red indicates that the user is getting "warmer", and blue indicates that the user is getting "colder". If the user has gotten no closer than the previous guess, set the background to white. Also, the background shouldn't change until the second guess, because on the first guess, there's no "previous guess" to compare with.
A JLabel should display either "Too High" or "Too Low" after each guess, to help the user zero in on the correct answer.
When the user gets the correct answer, "Correct!" should be displayed in the JLabel, the JTextField used for input should be changed to uneditable, and a JButton should be provided to allow the user to play the game again. If this JButton is clicked, a new random number should be generated and the input JTextField changed back to be editable (and the process starts over with a new round).

Filename: Guess.java

Note that input of guesses must be done in the JTextField, and event handling must be used. You may NOT use JOptionPane dialog boxes to get the input
This should run as a Java application, so remember that your outer level container should be some sort of JFrame
When you change the background color, this means the background of the whole frame (not just the text component, for instance).
Any member data (static and instance variables) of classes you write should be private
Make sure your code is appropriately documented and easy to read
Some classes/Interfaces you'll probably want to look at:
- JFrame
- JPanel
- JButton
- JLabel
- JTextField
- ActionListener (interface)
- ActionEvent

Submit your program in the usual way, through the web submission page.
