Collection class in leJOS HELP

[win1for]

Hi Guys,

I am trying to use LinkedList in leJOS but anytime i try to upload, i get an error that says:


421: cannot find symbol
symbol : class LinkedList
location: class receiver.NXTReceiver
LinkedList<Node> queue = new LinkedList<Node>();

What collection class should i use?

Try removing all the the standard java jars from eclipse project classpath so you can only use those classes what are really available in NXJ.

Exactly. Only the classes.jar must be part of your project configuration. Kick out any other JDK.

Thanks. After removing the JRE System libraries it works now.
