Question

(Java) Write a code segment that uses a for loop and an in a statement to determine whether the value 13 is stored in a previously declared dimensional array named sportsScores. If the value 13 is stored in the array, then store the value true in a boolean flag variable named found. Otherwise, store false in found. The array sportsScores has 4 columns and 5 rows.

Answer 1

//Java code

public class Main {
    public static void main(String[] args)
    {
        //The array sportsScores has 4 columns and 5 rows.
        int[][] sportsScores = new int[][]{
                {4,5,6,7},
        {3,4,5,6},
        {7,8,9,10},
        {5,3,2,1},
        {13,12,11,11}
            };
        boolean isContains13 = findValue(sportsScores);
        System.out.println("sportsScores array contains 13: "+isContains13);
    }

    /**
     * code segment that uses a for loop

     */
    private static boolean findValue(int[][] sportsScores )
    {
        boolean found = false;
        for (int i = 0; i <sportsScores.length ; i++) {
            for (int j = 0; j <sportsScores[i].length; j++) {
                if(sportsScores[i][j]==13)
                    found = true;
            }
        }
        return found;
    }
}

//Output
