Scheme doesn't have that many distinguishing features: 1) Garbage collection 2) Dynamic typing 3) No distinction between primitive values and general values - a value can be used everywhere 4) Lexical closures and higher-order functions 5) A hygienic macro system 6) First-class continuations 7) Space safety guarantees for tail calls ('tail call optimization') 8) A numeric tower 9) S-expression syntax 10) A focus on cons cells and lists as primitive data structures There's probably something I'm missing, but the only feature that Java shares is the first.
