scala猜拳小游戏

Scala猜拳小游戏是一个简单的命令行游戏，玩家可以与计算机进行猜拳对战。以下是一个简单的实现示例：

import scala.io.StdIn
import scala.util.Random

object RockPaperScissorsGame {
  def main(args: Array[String]): Unit = {
    val validChoices = List("rock", "paper", "scissors")
    val random = new Random()

    println("Welcome to Rock-Paper-Scissors game!")
    println("Enter your choice (rock, paper, or scissors):")

    val playerChoice = StdIn.readLine().toLowerCase()
    if (!validChoices.contains(playerChoice)) {
      println("Invalid choice. Please choose again.")
      return
    }

    val computerChoice = validChoices(random.nextInt(validChoices.length))

    println(s"Player chooses $playerChoice")
    println(s"Computer chooses $computerChoice")

    if (playerChoice == computerChoice) {
      println("It's a tie!")
    } else if (
      (playerChoice == "rock" && computerChoice == "scissors") ||
      (playerChoice == "paper" && computerChoice == "rock") ||
      (playerChoice == "scissors" && computerChoice == "paper")
    ) {
      println("Player wins!")
    } else {
      println("Computer wins!")
    }

    //
