Sounds kinda-array-ish. Can't you just create the array then fill it up with as much stuff as you want? Or was that just the example that I kinda misconstrued?

The problem when adding things to an array, is with java you need to define the array size, and you're not sure how big this is going to be (for example, adding CDs to my java program, http://www.bluetrait.com/projects/dca/).
With PHP the array will just increase if needed. Java doesn't do this.

An array would obviously make sense for storing multiple values, but I was thinking more along the lines of initializing variables in JavaScript, for use in manipulating the DOM.
So... with that for loop, not only could you initialize the variables, you could also do some basic initialization tasks, to each variable - provided it was the same for all variables.

Sounds like a job for variable variables. Don't know if javascript can do it but php can. You make the value of a variable the variable. I don't know what the use of this would be. Sounds like you may be over thinking somethings. I'd be interested in seeing an application of this.

Tim, yeah, that's kinda what I'm getting at. I looked at that link.. Wow.. gets pretty confusing. All those dollar signs and conversions - I bet it's hard to keep "straight," in the head.

This comment is for Michael:

If you need an array that can grow, why not just use a List? I use Lists ten times as much as I use arrays in Java. The Java Collections framework is enormously useful.

Use something along these lines:
import java.io.; import java.util.; //before the main class public static String variable_name;
//end of before main class
FileOutputStream fout;
try
{
fout = new FileOutputStream("variables.var");
}
for (int y =0;y while (in.ready())
{
String text = in.readLine();
System.out.println(text);
} catch (Exception ex1)
{
System.out.println ("Exception ex1 has occurred.");
}
} From there, you can just grab the output from the file, or from the output your program just gave. It probably has a few syntax errors, but those are easily fixed.

Oh dear, the formatting was all lost...clean it up, and it should work decently

Let’s say I want to quickly create five new variables, with a for loop...

You should be able to do that. I needed to for one of the java things I was doing.
