Actually if you are running through the full list of n entities and comparing them against n-1 other entities, then for the first entity in the list, call it a, you will have to check against b through n, but on checking b you will not have to check it against a (since a was just checked against b in the prior step) or itself, so you would check from c through n... and so on for each remaining entity. This essentially looks like:

for (int i = 0; i < entities.length; i++)
{
   Entity e1 = entities[i];
   for (int j = i+1; j < entities.length; j++)
   {
       Entity e2 = entities[j];
       if (isColliding(e1.rect, e2.rect))
           resolveCollisionFor(e1, e2);
   }
