    Default Spreadsheet data - linked list or hashmap

    Hi,

    I am looking to implement a spreadsheet in java. Would it be better to use a linked list (rows) of linked list of cells (columns) to store the data or a hashmap (each cell maps to a key e.g. A1 -> 1, A2-> 2 etc.)?

    Or is there an even better data structure to use?

    Thanks!

    Depends on what you're looking to optimize for. Using a plain array/ArrayList could also be an option.
