import java.util.Random; // Importing the Random class from java.util package
import java.util.Scanner; // Importing the Scanner class from java.util package

 public class RockPaperScissors { // Defining a public class named Rock Paper Scissors
 
 public static void main(String[] args) { // Defining the main method

Scanner scanner = new Scanner(System.in); // Creating a new Scanner object for user input

while(true) { // Starting an infinite loop

String[] rps = {"r", "p", "s"}; // Creating an array with the possible moves: rock, paper, Scissors
String computerMove= rps[new Random().nextInt(rps.length)]; // Geneating a random move for the computer

String playerMove; // Declaring a variable to store the player's move

while(true) { // Starting another infinite loop for validating player input
System.out.println("Please enter your move (r, p, or s)"); // Prompting the player to  enter their nove
playerMove = scanner.nextLine(); // Reading the player's move from the console
if (playerMove.equals("r") || playerMove.equals("p") || playerMove.equals("s")) { // Checking if the player's move is valid
break; // Exiting the loop if the player's move is valid
}
System.out.println(playerMove + "is not a valid move." ); // Printing an error message for invalid moves
}

System.out.println("Computer played: " + computerMove); // Printing the computer's move

这就是错误：
