[StringBuffer](http://docs.oracle.com/javase/7/docs/api/java/lang/StringBuffer.html) Re: Java Hangman StringBuffer objects 15 Years Ago by Alex Edwards You could just create your own collection-type, such as a linked list or a tree, to store your information. Edit: Also I think a StringBuffer is backed by an array for random-access character retrieval. Re: Java Hangman StringBuffer objects 15 Years Ago by snoh7 Sorry i'm a bit of an amateur at Java programming so i'm not exactly sure what your post meant. Is there a way i could do it using StringBuffer methods as that is one of my assignment requirements? i just need to somehow replace for example _ _ _ _ _ _(street) and s is guess with s _ _ _ _ _ Thanks for your speedy reply, appreciate it Re: about StringBuffer class 11 Years Ago by bguild The capacity 44 is two plus twice the old capacity of 21. In other words `sb.capacity() = 44 = 2 * 21 + 2`. That's what the documentation for `ensureCapacity` says it should be. I hope everyone is aware that `StringBuilder` is superior to `StringBuffer`.

Re: String vs Stringbuffer 13 Years Ago by masijade P.S. unless the spot where you're using a StringBuffer is "thread" sensitive, use a StringBuilder rather than a StringBuffer.
