Need help trying to get output correct to two decimal places.

[Reacz]

Hi, I have a problem, I'm trying to write a currency converter and have a problem, I want it to be correct to two decimal places, while I have got it to work, when I have two zero's after the point it only displays one, ie: 250 inputted by the user would be outputed like this: 250.0 instead of the 250.00 I want, my code is below, any help would be much appreciated.

import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.util.StringTokenizer;
import java.io.IOException;

public class Currency {

public static void main(final String[] pArgs) throws IOException
{

final BufferedReader tKeyboard =
new BufferedReader(new InputStreamReader(System.in));

System.out.println("Type currency converting from, to, conversion rate and the amount.\n");
System.out.println("Seperate them with a space: \n");
String tLine = tKeyboard.readLine();
StringTokenizer tTokens = new StringTokenizer(tLine);
String tFromString = tTokens.nextToken();
String tFrom = tFromString;
String tToString = tTokens.nextToken();
String tTo = tToString;
String tExchangeString = tTokens.nextToken();
double tExchange = Double.parseDouble(tExchangeString);
String tTotalAmountString = tTokens.nextToken();
double tTotalAmount =
Double.parseDouble(tTotalAmountString);

double tTotal1;
double tTotal2;
int tTotal3;
int tTotal4;
double tAmountc;
double tAmounte;
//------------------------------------------------\\
//Calculation for Exchange Rate.\\
//-------------------------------------------------\\
tTotal1 = 1/tExchange;

tAmounte = 100.0;

tTotal4 = (int) (tTotal1 * tAmounte + 0.5);

double tAmounte2 = tTotal4/tAmounte;
//--------------------------------------------------\\
//Calculation for Output Amount.\\
//--------------------------------------------------\\
tTotal2 = tExchange * tTotalAmount;

tAmountc = 100.0;

tTotal3 = (int) (tTotal2 * tAmountc + 0.5);

double tAmountc2 = tTotal3/tAmountc;
//---------------------------------------------------\\

System.out.println("\t " + tFrom + "\t " + tTo);
System.out.println("\t 1.00" + "\t " + tExchange);
System.out.println("\t " + tAmounte2 + "\t 1.00");
System.out.println("\t " + tTotalAmount + "\t " + tAmountc2);

}
}

Thanks

here is a small example of how to use the decimal format class:

import java.text.DecimalFormat;
import java.text.DecimalFormatSymbols;

    float X,Y = //some numbers;
    String format1 = "###0.00" ;  

    static DecimalFormat fm1 = new DecimalFormat( format1,
                                   new DecimalFormatSymbols(Locale.US));
    
    System.out.println("X=" + fm1.format(x) + ", Y=" + fm1.format(y));

this will always printout to 2 decimal places
