Question

What is the correct code to do this:

a new method called calculatePercentage with parameters int exam[][] int percentages[] and returntype void?

The method has to calculate all the percentages which have been stocked in int exam[][]. The objects stored in this exam[][] are results on /20. The percentages have to be on /100.

Thank you very much because I have no idea that works.

How the data in exam[][] is inserted

private void insertExamResults(int array[][])
    {
        int[] exam = new int[3];
        for (int teller = 0; teller < 3; teller++)
        {
            int i = 0;
            exam[i] = Integer.parseInt(JOptionPane.showInputDialog("Exams of student " + teller + " (max = 5)"));
            i++;
        }
    }

The new method I wrote:

public void calculatePercentage(int exam[][], int percentages[])
    {
        for (int i = 0; i < 3; i++)
            for (int j = 0; j < 5; j++)
            {
                //code for the sum of all elements on row
                            //stock this new value in a new array percentages[]
            }
    }

The double array exam has 3 rows and 5 colums.

Start from something like this:

for (int i=0; i < 8; i++)
   for (int j=0; j < 8; j++)
      board[i][j] = i+j;
