java uses ArrayList to realize landlord fighting (disordered version)

In this paper, we share the specific code of java using ArrayList to realize landlord fighting for your reference. The specific contents are as follows

Case introduction

According to the rules of fighting landlords, complete the action of shuffling and dealing cards. Specific rules:

Use 54 cards to disrupt the order, 3 players participate in the game, 3 people alternately touch cards, each with 17 cards, and the last 3 cards are reserved as cards.

Case analysis

Step 1 Prepare cards

Each playing card consists of two parts: color and number. The assembly of playing cards can be completed by nesting the color set and the number set iteratively.

2. Licensing

After the playing cards are transferred, they are disrupted and rearranged by Collections shuffle method, and the last three cards are used as cards, and the remaining cards are dealt in turn by taking the mold of three cards.

3. Look at the cards

Print the collection.
