Create a target practice game that allows the user to click moving targets and displays the number of hits in a 10-second period. Create a grid of at least 100 JPanels. Randomly display an X on five panels to indicate targets. As the user clicks each X, change the label to indicate a hit. When all five Xs have been hit, randomly display a new set of five targets. Continue with as many sets as the user can hit in 10 seconds. (Use www.oracle.com/technetwork/java/index.html to find how to use the GregorianCalendar class method getTimeInMillis() to calculate the time change.) When the time is up, display a count of the number of targets hit. Save the file as JTargetPractice.java.
