This article introduces the relevant knowledge of "how to use Java to achieve man-machine fist guessing Mini Game". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Stage 1: experiment-analyze the business and create user classes

1. Analyze the business, abstract the characteristics and behavior of the class 2. Create a user class

Stage 2: experiment-- create a computer class

1. Create the computer class Computer. Realize computer punching 2. Generate a random number of 1-3 to simulate the punching result of the computer.

Stage 3: experiment-- create a game class and choose to fight against your opponent.

1. Create a game class Game2. Write the initialization method of the game class initial () 3. Write the start game method of the game class startGame ()

Stage 4: experiment-- realizing a game against each other

Call the punching method showFist () of the user class and the computer class respectively, accept the return value and compare it, and give the result.

Stage 5: experiment-- achieve a round-robin battle and accumulate scores

Achieve a round robin and add up the winner's score

Stage 6: experiment-showing the results of the match

After the end of the game, show the results of the game and write the showResult () method, compare the scores of the two, and give the results of the game.

Stage 7: experiment-- perfecting the startGame of games ()

Enter and save the user name, and display the respective scores of both sides at the end of the game.
