(In Java) In the game Clacker, the numbers 1 through 12 are initially displayed. The player throws two dice and may cover the number representing the total or the two numbers on the dice. For example, for a throw of 3 and 5, the player may cover the 3 and the 5 or just the 8. Play continues until all the numbers are covered. The goal is to cover all numbers in the fewest rolls. Create a Clacker application that displays 12 buttons numbered 1 through 12. Each of these buttons can be clicked to ‘cover’ it. A covered button displays nothing. Another button labelled Roll can be clicked to roll the dice. Include labels to display the appropriate die images for each roll. Another label displays the number of rolls taken. A New Game button can be clicked to clear the labels and uncover the buttons for a new game.

(In Java) The SalesCenter application stores information about three employees. There is one manager (Diego Martin, salary $55,000), and two associates (Kylie Walter earning $18.50 per hour and Michael Rose earning $16.75 per hour). SalesCenter should be able to display the name and title for a specified employee. Additionally, the SalesCenter application should calculate and display the pay for a specified employee based on the pay argument entered by the user. The pay argument should correlate to hours worked if the pay for an associate is to be calculated. The pay argument for a manager should correlate to the number of weeks the manager is to be paid for. The SalesCenter interface should provide a menu of options. Depending on the option selected, additional input may be needed. Create client code that will generate the following SalesCenter output sketch: Employee/Pay/Quit Enter choice: E Enter employee number(1, 2, or 3): 2 Kylie Walter, associate Employee\Pay\Quit Enter…
