+1 to blake's comments. A couple more points, inline:

'Vector' has been out of date since 1998! It never ceases to amaze me that people still want to use it. I will bet dollars to doughnuts that the OP wasn't programming with Java yet in 1998. 2) Don't mix generics and Java arrays. It gets weird > That's putting it mildly. The Java Language Specification explicitly states, "... the element type in an array creation expression cannot be a parameterized type, other than an unbounded wildcard."

Note blake declares the variable 'articles' as type 'List' rather than an unnecessarily specific type, adhering to "Item 52: Refer to objects by their interfaces" from _Effective Java_ by Joshua Bloch. http://java.sun.com/docs/books/effective/toc.html Chris wrote: > >> articles = new Vector<Article>[9]; > > > > try articles = (Vector<Article>[]) new Vector[9]; > Again, neither of these is legal. You can get around it with '@SuppressWarnings', but shouldn't. The chapter on generics from _Effective Java_ [_op. cit._] is free to download and will help here. Take heed of "Item 23: Don't use raw types in new code". -- Lew -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
