Introduction To Java 9th Edition Chapter 22 Exercise 13 The 24-point game

(Game: the 24-point card game) The 24-point game is to pick any 4 cards from 52 cards, as shown in Figure 22.19. Note that the Jokers are excluded. Each card represents a number. An Ace, King, Queen, and Jack represent 1, 13, 12, and 11, respectively. You can click the Refresh button to get four cards. Enter an expression that uses the four numbers from the four selected cards. Each number must be used once and only once. You can use the operators (addition, subtraction, multiplication, and division) and parentheses in the expression. The expression must evaluate to 24. After entering the expression, click the Verify button to check whether the numbers in the expression are currently selected and whether the result of the expression is correct. Display the verification in a dialog box. Assume that images are stored in files named 1.png, 2.png, . . . , 52.png, in the order of spades, hearts, diamonds, and clubs. So, the first 13 images are for spades 1, 2, 3, . . . , and 13.
