实现扑克牌，一副牌中抽去大小王剩下52张（如果初练也可只用1～10这40张牌)，任意抽取4张牌（称牌组)，用加、减、乘、除（可加括号)把牌面上的数算成24。每张牌必须用一次且只能用一次，如抽出的牌是3、8、8、9，那么算式为（9-8)×8×3或3×8+（9-8)或（9- 8÷8)×3等。(In order to realize playing cards, 52 cards are removed from a deck (only 40 cards can be used for the first practice). Four cards are randomly selected (called card groups). The number on the deck is calculated as 24 by adding, subtracting, multiplying and dividing (brackets can be added). Each card must be used once and only once. If the drawn card is 3, 8, 8, 9, the formula is (9-8)*8*3 or 3*8+ (9-8) or (9-8 8)*3)

说明：  基础练习，这是Java入门课程的基础练习。包括了许多的知识点(Basic exercises, which are the basic exercises of the Java introductory course. It includes many knowledge points.)
