    variable variable names

    Hi guys,

    I am facing a problem in developing my application, scenario is like

    I am to declare and initiate a number of variables and I am not sure how many they can be, so I want to use variable names such as

    loop from 0 to n
    declare int VARIABLE_NAME plus Concatenate a number with its Name

    result will look like this

    VARIABLE_NAME_0
    VARIABLE_NAME_1
    VARIABLE_NAME_2
    ...
    VARIABLE_NAME_n

    Any suggestion, how it can be done ???

    Regards,
    Kashif Nawaz

    Re: variable variable names

    Well I really don't the answer to your question, but I have a sugesstion, see if it suits you...

    what I understand from your problem is that you get to know the number of variables needed only at run-time, and hence this is creating a problem...

    the most simple and effective solution i can think of is to use a vector or list instead, where vector[0] will act as variable0 and vector[1] will act as variable1 so on.

    will that solve your problem ?

    looking your scenario the best thing to implement is array; and be careful while working with J2ME, don't create variables unless it necessary as mobile phones have very little memory.

    Thanks
