I'm writing a program where stuff is placed in a treemap. I've gotten the map to work so that I can place stuff in it and evaluate it. However, when I want to place stuff in it in a static fashion I miss the syntax, I think. Pleace point out any other faults to.
private TreeMap<String, Sexpr> variables;
variables = new TreeMap<String, Sexpr>();
variables.put(String e, Sexpr Math.E);
