Adding args[1] to an int variable

    I recently wanted to make a money-like plugin and was working on a command that allows you to store a certain amount of money to your balance. I wanted to add args[1] of my /store command onto my balance variable, so adding a string to an integer, but I have no clue how I would have to do this. Any suggestions?

    Thanks in advance!

    So lets say I use /store 10 and I want to add the 10 to my balance integer, how would I then add it using parseInt? It keeps giving me the error that I can't add args[1] because it's a string even after using a parseInt function.

    Don't forget to trap errors in case someone fat fingers it and passes something non numeric.

    Sorry, I'm still very new to programming, but how would I then make it so the String args[1] is recognized as an int? I tried making a simple function like this:

    public static int toInt(String p) {
    return p;

    but it doesn't see p as an int but instead still as a string.

    I really appreciate the help!

    @DutchChris You need to return the Integer.parseInt(p)
    Not the p

    Ah that makes sense. I now have this line:

    balance += Integer.parseInt(args[1]);

    but it gives me an internal error when I run the command with this piece of code in it.

    Sorry for the amount of questions, hope you don't mind

    What error then? ArrayOutOfBounds? CastException?
