第一次个人编程作业

一、PSP表格

二、开发环境

• 操作系统：64-bit Windows 10

• 使用语言：Java

• JDK版本：jdk-16.0.1

• IDE：IntelliJ IDEA 2023.2.2

三、基本原理

项目内容

输入石头剪刀布的英文单词的字母开头大写,即会进行你和电脑的石头剪刀布

四、计算模块接口设计与实现过程

五、计算模块部分单元测试展示

import java.util.Random;
import java.util.Scanner;
​
public class RockPaperScissors {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        Random random = new Random();
​
        String[] choices = { "rock", "paper", "scissors" };
​
        System.out.println("Welcome to the Rock-Paper-Scissors game!");
        System.out.println("Enter your choice (rock[R], paper[P], or scissors[S]): ");
        String playerChoice = scanner.nextLine().toUpperCase();
​
        if (playerChoice.equals("R") || playerChoice.equals("P") || playerChoice.equals("S")) {
            String[] abbreviations = { "R", "P", "S" };
            int randomIndex = random.nextInt(choices.length);
            int playerChoiceIndex = -1;
​
            for (int i = 0; i < abbreviations.length; i++) {
                if (playerChoice.equals(abbreviations[i])) {
                    playerChoiceIndex = i;
                    break;
                }
            }
​
            if (playerChoiceIndex != -1) {
                String computerChoice = choices[randomIndex];
​
                System.out.println("Computer choice: " + computerChoice);
                System.out.println("Your choice: " + choices[playerChoiceIndex]);
​
                if (choices[playerChoiceIndex].equals(computerChoice)) {
                    System.out.println("It's a tie!");
                } else if ((choices[playerChoiceIndex].equals("rock") && computerChoice.equals("scissors"))
                        || (choices[playerChoiceIndex].equals("paper") && computerChoice.equals("rock"))
                        || (choices[playerChoiceIndex].equals("scissors") && computerChoice.equals("paper"))) {
                    System.out.println("You win!");
                } else {
                    System.out.println("Computer wins!");
                }
            } else {
                System.out.println("Invalid choice. Please enter R (rock), P (paper), or S (scissors).");
            }
        } else {
            System.out.println("Invalid choice. Please enter R (rock), P (paper), or S (scissors).");
        }
​
        scanner.close();
    }
}
