public static void main(String[] args)
{
Test myTest = new Test();

System.out.println(myTest.bumpMe(4, 25, true));

System.out.println(myTest.bumpMe(20, 10, false));
}

private
int bumpMe(int price, int increase, Boolean updown) {
if (updown)
{
return (int) Math.round(price + ((float) price * increase /
100));
} else {
return (int) Math.round(price -
((float) price * increase / 100));
}
}
