       public static void bubblesort(int[] list)
       {
assert list != null : "failed precondition";
           int temp;
           boolean changed = true;

for(int i = 0; i < list.length && changed; i++)
{
changed = false;

for(int j = 0; j < list.length - i - 1; j++)
                   {
assert (j > 0) && (j + 1 < list.length) : "loop counter j " + j + "is out of bounds.";
if(list[j] > list[j+1])
                   {
changed = true;
                       temp = list[j + 1];
                       list[j + 1] = list[j];
