Hello,

I am trying to get my cost, salestax, totalamount to come out in the output dialogbox to have only two decimals places. I know how to do on the printf but not on the dialogbox. Please help. Here in my complete code.

```
// Displaying multiple strings
import javax.swing.*; // to use JOptionPane.show InputDialog box
public class Assignment3
{
public static void main( String args[] )
{
final double taxes = 0.0825; // rate for taxes calculation (constant)
int
moreInt = 1, // loop control variable
days = 0; // the number of days wanted
double
totalPrice = 0, // the sum of calculated rental days
salesTax = 0, // the calculated sales tax
cost = 0, // fixed cost on the amount of rental days
totalAmount = 0; // the total amount for rental days
String numberDays; // number of days
String output = ""; // total rental message
String input = ""; // users input
// process unknown number of days, boolean controled loop
while ( moreInt == 1 ) {
numberDays = JOptionPane.showInputDialog(
"Enter the number of rental days" );
// convert numbers from type String
days = Integer.parseInt( numberDays );
// to determine the cost on the rental days
if( days >= 1 && days <= 3)
{
cost = 35.00;
}
else if( days >= 4 && days <= 7 )
{
cost = 30.00;
}
else if( days >= 8)
{
cost = 26.00;
}
// calculations
totalAmount = days * cost;
salesTax = totalAmount * taxes;
totalPrice = totalAmount + salesTax;
// message total output
JOptionPane.showMessageDialog(null, ("Car Rental Statement" +
"\n------------------------------" +
"\n" + days + " days $" + cost + " per day " + totalAmount +
"\nSales taxes @ 8.25% $ " + salesTax +
"\nTotal Price $ " + totalPrice +
" \n \n "));
// display the "Thank you" message
if (totalPrice < 100)
output = "Thank you - We hope to see you again!";
else if (totalPrice > 100)
output = "Thank you - We appreciate your business!";
// display message total
JOptionPane.showMessageDialog( null, output );
// display the "Another Rental" message
input = JOptionPane.showInputDialog(
"Another rental?\n 1 - yes\n 2 - no\n" );
moreInt = Integer.parseInt( input );
} //while loop ends
} // end method main
} // end method Assignment3
```
