How can I find the overall averages of the columns in this array?
when i run my code it gives me an output that looks like this (showing me wrong averages):
0 1 2 3 overall grade
Badger,Bradley 37 70 51 48 68.66666666666667
Emu,Emma 35 81 75 40 72.83333333333334
Aardvark,Alice 42 85 22 0 65.11111111111111
Dodo,Donald exc 12 25 0 54.17391304347826
Cassowary,Cassie 50 97 72 68 62.758620689655174
my code is :
Java Code:
public static double[] computeAllGrades(int[][] scoreTable, int[] itemPointValues)
{
{
double totalPoints = 0;
double totalPointsPossible = 0;
double allGrades[];
double grade =0;
allGrades= new double[scoreTable.length];
int k = 0;
for(int j = 0 ; j < scoreTable.length ; j++)
{
for(int i = 0 ; i < scoreTable[0].length ; i++)
{
if(scoreTable[j][i] == -1)
{
totalPoints = totalPoints + 0;
totalPointsPossible = totalPointsPossible + 0;
}
else
{
totalPoints = totalPoints + scoreTable[j][i];
totalPointsPossible = totalPointsPossible + itemPointValues[i];
}
grade = (totalPoints/totalPointsPossible)*100;
}
allGrades[k] = grade;
k++;
}
return allGrades;}}
