Q:

Ordering a list of 10 numbers

I have an  atomic integer array of size 10. I am using this array to organize numbers 1-10 sent in by threads. This 1-10 will eventually be able to change to be a range of numbers larger than 10 and the list is to contain the 10 greatest numbers in that range. I can see the numbers going into the loops and recognizing that they are greater than a number currently there. However, there is never more than 2 numbers in the array when it is printed out.  I have tried to trace my code in debug mode, however, it looks as if it is working as intended to me. I feel like there may be a simple error to my logic? I am completely sure all values are entering in the function as I have triple checked this. I start at the end of the array which should contain the highest value and then swap downwards once the slot has been determined. I would appreciate the assistance. This is just a simple experiment I am doing in order to grasp the basics before I try to tackle a homework assignment.
Here an example of my code:
 public class testing{

            static AtomicIntegerArray maxList = new AtomicIntegerArray(10); 
            final static int n = 10;

    static void setMax(int value)
            {

            for(int i = 9; i >= 0; i--)
            {       
                if(value > maxList.get(i))
                { 
                    int temp = maxList.get(i);

                maxList.set(i,value);

                if(i == 0)
                {
                    maxList.set(i, value);
                }

                else
                {   for(int j = i-1; j > 0; j--)
                    {
                        maxList.set(j, temp);
                        temp = maxList.get(j-1);
                    }
                }
                break;
            }
        }

    public static void main(String[] args)
    {
        for (int i = 0; i < n; i++)
        {
            setMax(i);
        }
    }
}

Here is an example of how it is being called:

A:

Brooke, there is a small bug in your 'j' loop.  You had saved the state of a variable (temp), however your logic in the j loop lost the state.  This new logic preserves the state of the previous element in the list.
Try this:
for (int j = i - 1; j >= 0; j--) {
    int t2 = maxList.get(j);
    maxList.set(j, temp);
    temp = t2;
}
