I heard one of my colleagues saying that Java handles recursion more efficiently than c or C++, I was just curious what why is it able to do so? I mean what is “under the hood” process that makes this happen.
All efforts appreciated.
The usual issue around recursion (not 100% sure this is what your colleague was referring to) is whether ‘it’ (the compiler, the JIT, the runtime, whatever) can (and does) implement ‘tail call optimization’. The goal is that instead of having the code make ‘real’ calls (introducing a new frame onto the call stack) that recurse (either into the same function or through the same ‘cycle’ of functions), you can get the same effect without doing so.
The wikipedia page is pretty decent on describing it.
