Overview
This lab gives you practice writing simple graphical user interfaces (GUIs). Make sure your code includes:
- Correct Javadoc header comments, including Java Class name, description, @author and @version tags.
- Correct Javadoc method comments, including a description of what it does, along with @param and @args as appropriate.
- A comment at the end of each import line, indicating why you need to import that class. For example:
import javax.swing.* // for JOptionPane methods

Task 1: ThemeSelectGUI
Create a GUI application with two buttons side-by-side: one labeled [Blue/Yellow] and the other [Black/Green]. The former sets foreground to blue and background to yellow; the latter set foreground to black and background to green.
Task 2: ColorToggleGUI
Create a GUI application with two buttons stacked one on top of the other. The first button is labeled [Foreground] and the second [Background]. Clicking the foreground button toggles the foreground from blue to black back to blue etc. The background button toggles background from yellow to green.
Task 3: IncrementDecrementGUI
Create a GUI application with three components. In the center is a text field, with the initial value of '50' in it. To the left is a button labeled with the '-' sign, to the right a button labeled '+'. Clicking the [-] should decrement the value in the box by 5, down to a minimum of 0. Additional clicks of [-] when the value is 0 should be ignored (have no effect). Clicking [+] should increment the number by 5, up to a maximum of 100.
Task 4: ColorSelectGUI
Create a GUI application using a border layout. The center regions should contain some text (a couple of paragraphs; you can use a favorite poem or verse or even nonsense). Along the left is a column of buttons that set the foreground color of the text region; along the right is a column of buttons that set the background color. At the top is a sentence telling the foreground color; at the bottom a sentence telling background color. Clicking any button should set the corresponding section to the appropriate color.
