ArrayListcan be a pool container, but it isn't an object pool itself. It needs some algorithmic support to implement caching.If you, for example, keep track of the head and the tail of the array instead of adding/removing objects to/from the array as it should be, you'll get some kind of manual memory management. Your objects won't be deleted and will probably be reused. Thereat you'll have the right to say that your program uses The object pool pattern.
