Syntax error in collection

You are missing the name of the variable (or field if the declaration is at class level) after ArrayList<Integer> - something like:ArrayList<Integer> myList = new ArrayList<Integer>();

Did you check your command line javac version? You may want to checkjavac -J-version it should print something like java version "1.5.0_06"i.e., you can use generics only with JDK 1.5.0 or above.
