This article mainly introduces the relevant knowledge of "how to use Java code to achieve a simple card game". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how to use Java code to achieve a simple card game" can help you solve the problem.

Function description

1. Create playing cards. Including four kinds of colors (spades, hearts, clubs, diamonds), thirteen points (2-10 JMagQ Q ·K), regardless of the size of the king.

2. Create two players. Including the player id, name, hand, etc., the hand is a collection of playing cards.

3. Shuffle the cards. The created playing cards will be disrupted.

4. Licensing. The shuffled cards will be collected, starting from the first card, issued to two players, installed in the way of one card per person, each issued two cards.

5. Games. Compare the cards in the hands of two players. The rule is: compare the cards with the largest points on the hands of two players, and win if the points are the same, compare them according to the color flowers.

Difficulty analysis:

1. Shuffle cards and how to disrupt playing cards. (main knowledge points Random,list.contains ())

2. How to compare the size of playing cards. (main knowledge points collections.sort (), comparable)
