    Default Help With Multidimensional Arrays

    Hello Guys, Here I am again with another question. I have been having trouble trying to create and initialize arrays. I need to create a multidimensional array and have tried everything but always got hundreds of error messages. Please can you give me some hints on this? Here is the example I am trying to create:

    private String currData[] [] = new String [3] [5];
    currData [0] [0] = {" Dollars"};
    currData [0] [1] = {" Euros"};
    currData [0] [2] = {" Reais"};
    currData [0] [3] = new String " Swiss Francs";
    currData [0] [4] = new String{" Pounds"};
    currData [1] [0] = " Cents";
    currData [1] [1] = " Cents";
    currData [1] [2] = " Centavos";
    currData [1] [3] = " Cents";
    currData [1] [4] = " Pence";
    currData [2] [0] = " US$";
    currData [2] [1] = " "€";
    currData [2] [2] = " RS$";
    currData [2] [3] = " CHF";
    currData [2] [4] = " £";
    As you can see, I have tried several ways and it never compiles.
    Thanks for any help.

    it never compiles.
    When you get errors, you should copy the full text of the error message and paste it here.
    Without the error message we may be guessing.
    If you don't understand my answer, don't ignore it, ask a question.

    I am using Javac to compile and cannot copy and paste from Command Prompt. The case is: If a create and initialize the array inside a class just for it, it works fine but if I try to initialize the array together with other variables, it does not work. It is so strange.

    --- Update ---

    For example:
    String currData[][] = new String [3][5];
    currData[0][0] = " Dollars";

    The second statement causes 7 errors: For example: "]" Expected, ";" Expected, Illegal start of type and so on.

    Any idea anyone? Thanks a lot.

    To copy the contents of the command prompt window:
    Click on Icon in upper left corner
    Select Edit
    Select 'Select All' - The selection will show
    Click in upper left again
    Select Edit and click 'Copy'

    Paste here.

    What errors do you get with the 2 lines in post #3?

    Where are those lines located in the source? The second line needs to be in a method.
    If you don't understand my answer, don't ignore it, ask a question.

    Thanks a lot. I just found out that the second part have to be in a method. That's why it wasn't working. it is fine now, thank you.
