Trying to use a generic class:

I copied this Stack class from a book, but it wont compile,
bugging on the 1st line:

class Stack<Item>  ( unexpected token "<" )

Any suggestion ?

//
//Stack = Stack as a Simply-Linked List, storing items
//====================
class Stack<Item> {
 private int count;
 private Node head;

 Stack<Item>() {
   head=null;
   count=0;
 }//Stack

 boolean isEmpty() {
   return (head==null);
 }

 void reset() {
   head=null;
   count=0;
 }//reset()

 void push(Item item0) {
   head=new Node(item0,head);
   count++;
 }//push()

 Item pop() {
   Item v=head.item;
   head=head.next;
   count--;
   return v;
 }//pop()

 //====================
 private class Node<Item> {
   private Item item;
   private Node<Item> next;

   Node(Item item0) {
     item=item0;
     next=null;
   }

   Node(Item item0,Node<Item> next0) {
     item=item0;
     next=next0;
   }

 }//private class Node

}//class Stack

this is not gonna work (i think), because Processings precompiler (ANTLR) will still have problems with the java-1.5 syntax.

Thank you all for the informations and references.
So I will forget about generics,
I can do without them anyway.
