![Throughout the semester, we have been working on command line applications. While the
command line can be a powerful form of interacting with the computer, most modern
applications have a graphical user interface, or GUI. This program will give you some initial
experience making GUI applications with Swing.
1. Write an original GUI application in Java using Swing. The program can be a simple game, or
an application that demonstrates some of the capabilities of Swing, for example.
2. The application must do something non-trivial that is controlled by GUI components such as
buttons, text boxes, drop-down boxes, etc. For example, it might draw different things, or change
colors, based on button presses.
3. The GUI elements should be layed out reasonably using layout managers.
4. At least one element in your GUI program besides the title bar must include your name.
Suggestions
Get the skeleton of your GUI working first. First get the buttons drawing properly, then go on to
listen to and respond to events.
Initially, hook up the event listeners so that they print something to the console when a button is
pressed. That way you can know that your code is getting events.
If your program will draw shapes, make a subclass of JPanel called "DrawPanel" or something
like that to draw the objects and your name. Override the "paintComponent" method of this
class.

m1.add(m11); m1.add(m22); //Creating the panel at bottom and adding components JPanel panel
= new JPanel(); // the panel is not visible in output JLabel label = new JLabel("Enter Text");
JTextField tf = new JTextField(10);// accepts upto 10 characters JButton send = new
JButton("Send"); JButton reset = new JButton("Reset"); panel.add(label);// Components
Added using Flow Layout panel.add(tf); panel.add(send); panel.add(reset); // Text Area at the
Center JTextArea ta = new JTextArea(); //Adding Components to the frame.
