What Type/Gender is My Little Guy?

[Java]

All Pine Woods. They are all over where I live in Florida. I have owned a few in the past. Young-ish ones have an unbelly just like the one seen in the picture. As they get older, they get a bright spots on the underside of their legs (which you can start seeing on the one posted for identification..). When they start changing to brown, spots are more noticeable to clearly noticeable on their backs.

There.
