# Exercise 9: Modifying Clock

In this exercise, you will make a change to the Clock bean and rebuild the bean. When you are done, the version of `Clock.jar` in the Beans project will be different than the version in the DeskClock GUI project.

1. Open the Project Manager window and double-click the project name `Clock` in the project list.

   If you did not quit the DeskClock project after the previous exercise, you will be asked if you want to save and quit the current project; click Save and Quit. Click Switch in the next dialog box to change projects.

2. After the Clock project is opened, open the `Clock.java` file by double-clicking on `Clock.java` (in the Clock project file list) in the project manager.
3. In the source editor, scroll to this line in `Clock.java`:
   `monthFont = new Font("Helvetica",Font.ITALIC,8);`
   and change the font size of `8` to `12`.

   If you cannot edit , check to see that you have changed the permissions for the file.

4. Click Save on the Edit/Debug toolbar to save your edits.
5. Click Build on the main toolbar to compile your file.
