Little Help

[IWanna4get]

I'm new to java >.>
i seem to be having a problem in having a program in money denomination i'm suppose to use while loop the process is complete and no errors but the out put solution is wrong like when i type 800 it goes

1000:0 500:1 200:-0 100:6

which is weird :p


any advice is open and i'll keep working on the money denomination thingy :D

also a character identifier ex: i typed Hello 45!!!
output:
H-Consonant Letter
e-vowel letter
l-Consonant Letter
l-Consonant Letter
o-vowel letter

4-even number
5-odd number

!-especial character
!-especial character
!-especial character

i dunno how to use an array and the tutorials i'm reading are not making any sense -.-

Does this tutorial make any sense?

The crystal ball is in the shop, so it's hard for me to discern what is presently wrong with your code. Why not post it here?

import javax.swing.*;
import java.text.*;
public class money{
public static void main(String[]args){
DecimalFormat formatter = new DecimalFormat("#0");
String P="";
double p=0.00;
double a=0;
double b=0;
double c=0;
double d=0;
double e=0;
double f=0;
double g=0;
double h=0;
double i=0;
double j=0;
double k=0;
double l=0;
double m=0;
double n=0;
do{
P=JOptionPane.showInputDialog(null,"Enter Value:");
p=Double.parseDouble(P);
while(p>999){
a=(p-(p%1000))/1000;
{break;}}while(p>499){
b=((p-(a*1000))-(p%500))/500;
{break;
}}while(p>199){
c=((p-(a*1000))-(p%200))/200;
{break;}}
while(p>99){
d=((p-(b*500)-(c*200)))/100;
{break;}}

JOptionPane.showMessageDialog(null,"You Have\n1000= "+(formatter.format(a))+ "\n500= "+(formatter.format(b))+"\n200= "+(formatter.format(c))+"\n100= "+(formatter.format(d)));
}while(JOptionPane.showConfirmDialog(null,"Again?" )==0);
}


}

try 500 or 600
it's wrong the decimal formatter is rounding it off >.<

sadly i deleted the file with the 200 since its not getting fix,, how can u remove the decimal without rounding it off?

So is this program trying to calculate which of the 'bills' to give back as change or something?

You really should label things with readable/logical names. Using letters is bad practice, unless you are doing a simple loop and using it as an iterator or something...

This program is a money denominator ex:

i input 5600

output: you have
1000=5
500=6
200=0
100=1

in short it shows what the value is made of (the value is currency :p)
