And he's right. I don't know how many rangecheck() functions that I've cobbled together quickly to stop a program from doing stupid stuff with garbage data.
private int rangeCheck(int x, int y)
This simplistic example just tweaks data, something most programmers can do in their sleep. To suggest that a bounds check algorithm takes six months is laughable. That said, why would Google need to rip a limiter from oracle anyway? I have found that plugging in someone else's code can sometimes make a project take longer than if you just hack it together yourself anyway.
