22,441 programmer developer interview questions shared by candidates

question like: ArrayList list = new ArrayList(); for (i =0; i < 10000;i++) { list.add(i); } do you see a problem here ? you add to answer that this list is slower than the new List object and there is a danger of mixing different object type in the same list. I didn't event think of that because you are looking for the catch. and it goes on like this the hole interview.
