a. Search the Java website for information about how to use a JTextArea, its constructors, and its setText() and append() methods. Write an application that allows the user to select options for a dormitory room. Use JCheckBoxes for options such as private room, Internet connection, cable TV connection, microwave, refrigerator, and so on. When the application starts, use a text area to display a message listing the options that are not yet selected. As the user selects and deselects options, add appropriate messages to the common text area so it accumulates a running list that reflects the user’s choices. 

Save the file as JDorm.java.

b. Modify the JDorm application so that instead of a running list of the user’s choices, the application displays only the current choices. Save the file as JDorm2.java.
