silly string array question
Aug 25^th, 2007, 1:57pm

Hi, this is my first post and already a pretty silly question I guess, but I can't figure out why it is like it is:

So, this works outside of void setup()

Code:


String[] toggleDimensionText = {"Mode: 3D","Mode: 2D"};

but this doesn't:
Code:


//outside of void setup()
String[] toggleDimensionText = new String[2];
// only works if inside of void setup()
toggleDimensionText[0] = "Mode 3D";
toggleDimensionText[1] = "Mode 2D";

The last example only works if I put the last two lines inside of void setup() and I can't figure out why???

The error message is 'unexpected token: void'

I thank you for any help and many thanks also to the developers for having created Processing!

it's just the semantics of the language. a simple way of putting it is that the code outside setup() is not read sequentially, so that type of syntax is disallowed (it's something we inherit from java). so basically, because there's no guarantee that "new String[2]" will run before "toggleDimension[0] = ...". because of the messiness of how such code would compile, it's just not allowed.

In a pure Java environment, where would these commands outside of setup or any other function stand?
