My generic array creation problem.

Question

I'm getting a "generic array creation" error on lines 6 and 14. I've googled it and I'm still having a hard time. Most things I find on it are pretty complicated and as you can see mine's not, I'm in a beginners course. I'm basically writing a class with methods for dealing with a file of donors.
Here's my code:
public class DonorList <dlist>
    //Create empty list
    public DonorList()
        storage = new dlist [MAX];
        count = 0;
    //Capacity as specified
    public DonorList (int cap)
        MAX = cap;
        storage = new dlist [MAX];
        count = 0;
    public boolean isEmpty()
        return count == 0;
    public void clear()
        count = 0;
    //Returns number of elements
    public int size()
        return count;
    //Item at position k, position starts at zero
    public dlist get (int k)
        if (k >= 0 && k < count)
            return storage [k];
        return null;
    // e becomes item at position k
    public dlist set (int k, dlist e)
        dlist old = null;
        if (k > 0 && k < count)
                old = storage [k];
                storage [k] = e;
        return false;
    //Returns the position of e or -1 if not found.
    public int indexOf (dlist e)
        int k;
        for (k = 0; k < count; k++)
            if (e.equals(storage[k]))
                return k;
        return -1;
    //Appends e at the end of the list. Returns false on failure.
    public boolean append (dlist e)
        if (count < MAX)
            storage [count] = e;
            count ++;
            return true;
        return false;
    //Adds e at position k. Returns false on failure.
    public boolean add (int k, dlist e)
        int j;
        if (count == MAX || k < 0 || k > count)
            return false;
        for ( j = count; j > k; j--)
                storage [j] = storage [j-1];
                storage [k] = e;
                count ++;
                return true;
        return false;
    private int MAX = 100;
    private dlist [] storage;
    private int count;
}Any help as to why I am getting these errors is very much appreciated. Thanks.

Answer 1

You cannot create an array of a generic, instead you need to create an array of the class the generic extends (in this case Object)
You then have to cast the array to the generic type which will give you an unchecked warning which you can turn off with @SuppressWarning("unchecked") on the class.
Generics and arrays don't always play nicely together and this is one case. ;-)
