Answer to Question #278358 in Java | JSP | JSF for Mark18

Question

create method

parameters: string array and integer variable

return: integer variable max

method will receive a string array containing scores for a single day and return the id of the player with maximum score

For a day “12,0-234,1-23,3-201,2-1”. The array would be arr [0] is a string “12”

arr [1] is“0-234”arr [2] is“1-23”arr [3] is“3-201” arr [4] is“2-1”

assume ply.txt file is used

While the first element is game points for that day, other elements are player id and their score for the day.Using a loop,we need to process each players score.We will extract the player id and their score (string indexOf, substring and Integer.parseInt). After finding it, it should place the score for player in a temporary array for players. Then it should find the id of player with highest scores.

For this, create a temporary array Scores and store score of player 0 in Scores[0], score of player 1 in Score[1] and so on.

This method will return max as the id of the playerwith highest score for the data of day in inputarray arr.

Answer 1

public class Main {
    public static int findMax(String[] dayScores, int players) {
        int max = Integer.MIN_VALUE;
        int id = -1;
        int[] scores = new int[dayScores.length - 1];
        for (int i = 1; i < dayScores.length; i++) {
            String[] player = dayScores[i].split("-");
            scores[Integer.parseInt(player[0])] = Integer.parseInt(player[1]);
        }
        for (int i = 0; i < scores.length; i++) {
            if (scores[i] > max) {
                max = scores[i];
                id = i;
            }
        }
        return id;
    }

    public static void main(String[] args) {
        System.out.println(findMax(new String[]{"12","0-234","1-23","3-201","2-1"}, 3));
    }
}
