In Java/C#, you need to specify a constraint on the sorts of types allowed in the array to sort.  For example, you might say that elements of the array must implement the Comparable interface.   But it's more complicated than that.   These sorts of constraints allow you to compile generic code independently of its clients.     On a related note, if you would like to see state of the art language design, try Scala. « Last Edit: Jun 15th, 2007, 5:03am by amichail » IP Logged DropZap - a new kind of block elimination game Pages: 1  Reply Notify of replies Send Topic Print Forum Jump: ----------------------------- riddles -----------------------------  - easy   - medium   - hard   - what am i   - what happened   - microsoft   - cs   - putnam exam (pure math)   - suggestions, help, and FAQ => general problem-solving / chatting / whatever ----------------------------- general -----------------------------  - guestbook   - truth   - complex analysis   - wanted   - psychology   - chinese « Previous topic | Next topic »
