variable to string to command

[donald croswell]

Hey all,
I am trying to get a variable to concatinate to a string then use that string as a command like this:
newx = place + "[" + num + "]";
Where place = "ones" and num = "8".

So my line new line is:
newx = ones[8];
This will make newx equal to the static string array "ones" in the "8" place.
I can get the concatination to the string but it doesn't treat the string like a command.
Thanks for the help!

Yes, all you did was assign the String value "ones[8]" to newx. You cannot use a String Object to represent a variable. If you want to assign the value in ones[8] to newx you have to use the variable name. If num is a String you'll have to convert it to an int first.

int i = Integer.parseInt(num);
newx = ones[i];

If places can hold other values besides "ones" you need to put this in a controll structure to determine which array to place it in.

int i = Integer.parseInt(num);
if(places.equals("ones"))
{
    newx = ones[i];
}
else if(....
