Need help with formating numbers

Question

public void returnDollars()
          double dollar;
          dollar=amountr-amount;
NumberFormat fmt = NumberFormat.getNumberInstance();
          System.out.println(fmt.fomat(dollar));
there is my code.....now lets say
amountr = 10
amount 8.5
now when i print my dollar amount i want it to show up as 1 not 1.5 or 2. So in other words format it with no decimals and not round up at the same time.
Help would be appriciated...thanks

Answer 1

well...after 8 hours of trying to get it working i did it.....here it is ...........I'm sure there are many ways to make it smaller.
