    Welcome bhasker4, to Java Forums! :D

    Recently I also imported data from excel documents into my database using Java. I read the spreadsheets using CSV and string scanning. I'm guess that you are trying to import the data by dynamically assigning a table to a spreadsheet depending on the data types. What I would rather do is to hard code which spreadsheet is for which table. The main problem with your approach is one we also get in OO programming. Signature ambiguity. For example, if you have two spreadsheets:
    Java Code:
    Vehicle(name : string, kilometers : integer)
    Person(name : string, age : integer)
    Which spreadsheet goes to which table? Rather code it explicitly. Or maybe, you can get professional software to automate this for you.

    Good luck bhasker4. ;)
