Answer 1

Sorry I write that wrong,
heres how it should be:
public class whileLoop{
int time, time2;
time = System.currentTimeMillis();
public timer()
while //watever//{
time2 = System.currentTimeMillis();
time2 = time2 - time;
system.out.println(time);
class use{
whileLoop a = new whileLoop();
public void main(String args[]){
a.timer();
}
