Dividing elements in two diferrent arrays

[BuhRock]

I am using an array to store 5 test scores. Then I have another array for the total possible score the test could have. I just need to find out what percent the grade is out of the total possible score.

public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        int[] grade = new int[5];
        int[] outOf = new int[5];
        int[] percents = new int[5];
        

        int total = 0;
        int average;
        int percent;

        grade[0] = 70;
        grade[1] = 65;
        grade[2] = 120;
        grade[3] = 150;
        grade[4] = 30;

        outOf[0] = 210;
        outOf[1] = 100;
        outOf[2] = 150;
        outOf[3] = 200;
        outOf[4] = 50;

        for(int i=0;i<grade.length;i++)
        {
            total += grade[i];

        }

        average = total / 5;

        System.out.println("The total is " + total + "\nThe"
                + " average is " + average);
        }
        
        for(int j=0;j<grade.length;j++)
        {
           
            
        }
}

You've got everything pretty much set up and good to go. Where you're probably encountering your problem is when it comes to casting. Because the variables are integers, calculating the percentage will reduce to 0.

You will need to cast to the proper format, then cast to integer. Like so:

PHP Code:

percents[j] = (int)( ( (float)grade[j] / (float)outOf[j] ) * 100 );
System.out.println( "Percentage of Grade " + j + " is " + percents[j] ); 


That code would go in that empty for loop of yours.
