In Java, create a game that helps new mouse users improve their hand-eye coordin

Question

In Java, create a game that helps new mouse users improve their hand-eye coordination. Within a JFrame, display an array of 48 JPanels (changed below) in a GridLayout using eight rows and six columns. Randomly display an X on one of the panels. When the user clicks the correct panel (the one displaying the X), remove the X and display it on a different panel. After the user has succesfully "hit" the correct panel 10 times, display a congratulatory message that includes the user's percentage (hits divided by clicks). Save the file as JCatchTheMouse.java.

Additionally, use 48 JButtons instead of an array of 48 JPanels. Once the user clicks on the tenth correct button, display the course id (CSC 102) by using a JOptionPane message dialog.
