how come i cant cast a char on a set??? it works well with other data types.
thanks in advance
Jump to Postchar is a primitive, you can't store primitives in Collections.
Make it Set<Char> instead, and autoboxing will ensure your chars are converted into Chars and back again.
Jump to Postyes, my bad. I rarely use that type, mostly we use longs where I work.
