Question

I’m trying to convert a char to Character before it gets pushed on a stack but get a “cannot find symbol error”, I don’t see what the problem might be. This is how I pass the char to the stack:

stack.push(valueOf(in));

Where ‘in’ is a char.

Answer 1

valueOf is a class method of Character, among others. You can’t just call it without a class to hang it off.

What you’re really looking for is

Character.valueOf(in) or new Character(in).
