Honestly, I do not understand your code much I just saw typical error ;-)
Normally, you would better use
int i = 0;
while(i<names.length){
...
i++;
}
your code maybe compile correctly but I would double check that it really
works as expected because I doubt that.
boolean foundName =false;
while(foundName==true){ // while is never executed because foundName is
false by default
