Hi Guys,

I just wanted to confirm. This compiles so in any type of legacy collection, primitives are going to be autoboxed right? Thanks!

Hi Bo,

I think you can yourself compile this code and see anyway i think it will work.I don't find any problem with that.


Thanks and Regards,

Hi Jart Bo,

It will work as long as it is Java 5. Prior to Java 5 there was no Autoboxing feature so probably give a compiler error.

What is normally meant by a "legacy collection" is one of the old collection classes (such as Vector or Hashtable), from Java 1.1, before the collections framework was added.

But I guess here you mean a collection without using generics.

Yes, primitive values will be autoboxed, also when using a collection without generics.
