print() or println()
Jul 24th, 2008, 4:51pm  
I am looking at Processing Handbook, trying to copy one example, which doesn't seem to be working.

----------
String[] trees = { "ash", "oak" };
trees = append(trees, "maple");
print(trees);
----------
Console:
----------
[Ljava.lang.String;@b753f8
----------

It gives me this.
Is there something wrong with the code above?
When I changed print(trees) to println(trees),
it works. I'm using 0135.
I'd appreciate any help.

example must be slightly dated.

from: http://processing.org/reference/print_.html
"Beginning with release 0125, to print the contents of an array, use println(). There's no sensible way to do a print() of an array, because there are too many possibilities for how to separate the data (spaces, commas, etc). If you want to print an array as a single line, use join(). With join(), you can choose any delimiter you like and print() the result. "

Yeah, sorry about that. It was a typo in the book, and we've fixed it for later printings:
