Question:

Rewrite Exercise 20.13 using JSF, as shown in Figure 33.34. Upon clicking the Refresh button, the program displays four random cards and displays an expression if a 24-point solution exists. Otherwise, it displays No solution.

The 24-point game is to pick any 4 cards from 52 cards, as shown in Figure. 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?Shuffle?button to get four new 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 label before the?Shuffle?button. 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.
