Import question ????
May 15th, 2010, 3:10am  
I'm wondering if it's necessary to import the following libraries in a processing source if I want to use ArrayList objects with all its utilities (ex: iterator method, ecc) :

import.java.util.List*;
import.java.util.ArrayList*;
import.java.util.Collection*;
import.java.util.Iterator*;


thanks  Smiley

Answer 1: the syntax you show isn't correct... Wink
Answer 2: just try (without them)... Smiley
Answer 3: I think it isn't necessary, Processing imports this package by default (IIRC).

sorry for the shynthax errors;
i've checked that even if I import (correctly Smiley ) those libraries the line

ArrayList<Object> obj = new ArrayList<Object> ();

gives an error (for the tokens '>' and '<'), but I know this is the correct way to declare an ArrayList of the Object type in Java,
is there another way to do it in processing?? or simple you can't specify the object type ????

Answer 1: In Processing 1.1, the Java 1.5 syntax isn't implemented, so you use it in the old way: ArrayList obj = new ArrayList();
Answer 2: If you feel adventurous (not so much, I use it and it is quite stable), you can download the latest version 0184 and use this syntax, as there is an experimental (ie. not fully tested, but the more people use it, the more tested it will be...) support of this syntax.
