Yes I have this in an array...

// Average Grade
                 for(int i = 0; i<10; i++);
                 {
                   System.out.print("Average Grade" + scoreArray[i]/10);
                 }

I am wanting to divide by 10 (where the 10 is) I know that it want let me but how would you divide a list of numbers that is in an array? or format it to?

Here is my complete program and it needs for the last part to devide all of the numbers in the array by 10.

public class Arrays
    {
    public static void main(String[] args)
         {

          // declare , initialize array
             int[] scoreArray =  {50, 21, 32, 99, 102, 0, 88, 98, 101, 88 } ;
          // print scores
             for(int i = 0; i<10 ; i++ )
       { 
          System.out.println("Score "+ i + " = " + scoreArray[i]);
       }
             // Highest Score
             for(int i = 0; i<10; i++);
             {
               System.out.print("Hightest Score =" + scoreArray[4]);
             }
             // Lowest Score
             for(int i = 0; i<10; i++);
            {
             System.out.print("Lowest Score =" + scoreArray[5]);
            }
             // Average Grade
             for(int i = 0; i<10; i++);
             {
               System.out.print("Average Grade" + scoreArray[]);
             }
    }
}

Smells like homework to me!

Anyway.. Firstly, I think you need to understand what the for loop does. So, when you write for(int i=0; i<10; i++) {...}, you need to keep in mind that everything in the curly brackets is going to be executed 10 times.

I'm guessing you were asked to write a program that finds the lowest, highest and average of an array. So, just doing scoreArray[4] wouldn't be the best solution. You need to write a program that does the job.

To find the maximum of an array, you need to go through all the entries and compare their value with a "current max". Similarly with minimum.

The average is a tiny bit more complicated but if you do maximum and minimum properly I'm sure you'll find it easy :)
