Fighting Landlords--Java

Design Ideas of Doudizhu:

1. Prepare cards: 54 cards, stored in a set

Special cards: King, King

Other 52 cards: define an array/set, store 4 suits: ♠, ♥, ♣, ♦

                      Define an array/set, store 13 serial numbers: 2, A, K,,,,,,3

Loop setting to traverse two arrays/collections, and assemble 52 cards: ♠2, ♠A,,,,,,,

1. Shuffle

Methods of using collection tools Collections

Static void shuffle(List<?> list) uses the specified random source to replace the specified list

Randomly disrupt the order of elements in the set

1. Licensing

Requirement: 1 player has 17 cards, the remaining 3 cards are the hole cards, and each card is dealt in turn: the index of the set (0-53)%3

Define 4 sets to store the cards and hole cards of 3 players

1. Look at the cards

Print the set directly, traverse the set storing players and hole cards
