Assignment This lab is designed to have students become fami

Assignment: This lab is designed to have students become familiar with advanced GUI concepts, such as JTextAreas, JLists, and JComboBoxes. It is also designed to provide a bit more practice with Object Serialization. Finally, it is written in such a way as to be functionally simple, but provide less direct guidance as a problem solving test. For this lab, you have been contracted to write simple color word, an ambitious competitor against Microsoft Word. Unfortunately, as your company only hired you, and have yet to offer you payment, they are unlikely to survive the free market economy. For your GUI, please create the below GUI. It is made of a JTextArea in the center, two buttons, a JList for background colors, a JComboBox for foreground colors, and a bunch of panels. The size I used is 600 by 600. but you do not need to use this size. Note that on the JTextArea, you SHOULD use setPreferredSize(new Dimension(300,500) to set a size for the TextArea. Finally, be sure to have a scroll pane on the TextArea When you select a new background color, the space around the text area should change. Foreground colors should change the color of the text area, as shown:
