  • 0

When I am executing a SQLite query (using sqlite4java) I am following the general scheme of executing it step by step and obtaining one row at a time. My final result should be a 2-D array, whose length should correspond to the amount of records. The problem I am facing is the fact that I don’t know in advance how many records are to be returned by my query. so I basically store them in an ArrayList and then copy pointers to the actual array. Is there a technique to somehow obtain the number of records to be returned by the query prior to executing it fully?

    My final result should be a 2-D array, whose length should correspond to the amount of records.

    Why? It would generally be a better idea to make the result a List<E> where E is some custom type representing “a record”.

    It sounds like you’re already creating an ArrayList – so why do you need an actual array? The Collections API is generally more flexible and convenient than using arrays directly.
