I need help!

[clement1]

Ok, i need help with a problem. Its a program that generates a random number, allows 3 guesses and has 8 rounds. It stores the guesses and calculates how many rounds the user guessed right then gives a little rating. Ive done this part. the next part is:

Finally, modify your program so that the game can be played by multiple players. When the program begins, a message is printed asking how many players will take part. A maximum of 6 players should be imposed. The computer generates ONE random number for each round. Each player plays 8 rounds, in which they take turns at guessing the generated random number. At the end of the 8 rounds, the program prints a message saying which player (or players) won the most games.

I dont know how to structure my program to do this. from the previous version, it goes through all 8 rounds first. How do i store the scores in ym array and then sort them for the winning players?

Any help is appreciated

I wouldn't store the scores in an array. I would create Player objects and store the scores there. I would store the multiple player objects in an array. Then during your game, I would just loop through this array. One trip through the array = 1 round.

What do you mean player objects? I am totally new to java only been doing it a few weeks and i havent touched on the object orientated side. I thought about a multi dimensional array to store the player number and their total win count but i dont know how to write these to the multi dimensional array.

Here's an idea in pseudo code:

Code:

public static void main(String args[])
{
    int[][] players_marks;

    no_players = getPlayers(MAX_PLAYERS);

    // The jvm initializes all array elements with the default value of zero.
    players_marks = new int [no_players][NO_ROUNDS];

    // If you count a win in any round as a 1 and a loss as
    // a zero this array will track the rounds won and lost
    // for each player:
    // any player = players_marks[playerIndex]
    // the rounds for any player = players_marks[playerIndex][roundIndex]
    // Each player will have an array of NO_ROUNDS length
    // that contains the score for each round of guesses.

    for (int times = 0; times < no_players; times++)
    {            
        for (int rounds = 0; rounds < NO_ROUNDS; rounds++)
        {
            //This displayes the current player
            currentPlayer = "Player " + (times + 1);
                
            // print round number
           
            //Generates random number.
                           
            //get 3 guesses from user and calculate if they 
            // guess the number using checkAnswer method.
            for (int count = 0; count < GUESSES_SIZE; count++)
            {
                compare = checkAnswer(usersGuess, randomNum); 
                hint = giveHint(randomNum, usersGuess);
               
                if(compare)
                {
                    winCount = (winCount + 1);
                    players_marks[times][rounds]++;
                    // or you could wait and set this equal to
                    // winCount after exiting the rounds loop.
                    break;
                }
                else
                {
                    if(count == (GUESSES_SIZE - 1)) 
                    {
                        loseCount = (loseCount + 1); 
                    }
                }
            }  
        }//end of rounds
   
        //Print the final win & lose count and display ranking.
        int totalWins = getPlayerWins(players_marks[times]);
        // winCount and totalWins should have the same value.
        // Print 8-round total of win data for this player.
        userRating = rating(totalWins);
    }//end of no players loop
} //end 

private int getPlayerWins(int[] playersRounds)
{
    int total = 0;
    for(int j = 0; j < playersRounds.length; j++)
        total += playersRounds[j];
    return total;
}

Thanks, i managed to write a method that stores the current highest score & player then compares it to the next score in the loop without using an array. It was a little assessment that i had to do so i didnt have time to sit and figure it out properly. I will try your suggestion tho and see what i can do with it.
