HW3: Using Threads

Define a class, say HW3Thread, extending the Thread class. The class should take a JTextArea type as one of the arguments for the construtor.
In the main applet, create say, three JCheckBox's and three JTextArea's. Use arrays. Also, create three threads of the above class. Hint: Do not start the threads in the init() method. Add ActionListeners to the checkboxes just like the buttons. In the actionPerformed method, you can call the boolean method isSelected() on a JCheckBox to see if it is selected or not.
When the checkbox is selected, the corresponding thread would print some lines in its associated TextArea. When the checkbox is unselected, the corresponding thread will be in a pause mode, and resume when the checkbox is again selected.
Look at the documentation for java.lang.Thread class, and do not use the deprecated methods like suspend, resume, etc. Also, the threads should not be in a busy loop mode. Make use of wait and notify.
