Help needed in Java

Description:The program basically lets the user input numbers from 0 - 99,999.9 which the program will convert the inputed number to it's equivalent words.

example

Input number: 3
World Equivalent: Three dollars

I have established to convert a ones digit.

Code:

public class NumberConvert
{
	/*
	 *Function name: main
	 *Description: This is where the main calls for a method(s). And from there it process
	 *			   the codes and prints them.
	 *Arguments: String args[]
	 *Return Type: none
	 *Known Bugs: 
	*/
	
	public static void main(String args[])
		throws Exception
	{
		System.out.println("Welcome to Money Conversion!" + "\n");
		String strContinue;
		String strInputs = "";
		do
		{

			Double dInput = ReaderData.getDoubleInput("Input number: ");
			String sInput = Double.toString(dInput);
			String WordEquivalent = "";
		
			for(int iCtr = 3; iCtr <= sInput.length(); iCtr++)
			{
				if(iCtr == 3)
				{
                                        // OOP
					NumberConvert obj = new NumberConvert();
					String Ones = sInput.substring((sInput.length() - iCtr), (sInput.length() - (iCtr - 1)));
					Ones = obj.getOnes(Ones);
					
					WordEquivalent = WordEquivalent + Ones;
				}
			}
			System.out.println("\n" + "Word Equivalent: " + WordEquivalent + " Dollars" + "\n");
			
			
			
			if(strInputs.equals(""))
			{
				strInputs = WordEquivalent;
			}
			else
			{	
				strInputs = strInputs + " , " + WordEquivalent;
			}
			
			strContinue = ReaderData.getStringInput("Do you want to continue? [Y/N]: ");
			System.out.println();
			System.out.println();
			if (strContinue.equals("n"))
			{
				System.out.println("\n" + "You have inputted: "+ strInputs + "\n" + "\n" + "\n" + "Thank you for using this program, Goodbye!" + "\n" + "\n");
			}
			
		}
		while(strContinue.equals("y"));
	}

------------------------

I'm still looking for a way to find the tens, hundreds and thosands value
eg.
45 = forty five dollars
123 = one hundred and twenty three dollars
3241 = three thousand and two hundred and forty one dollars





Any ideas? please help.



Thanks.

Use a switch to do this not a stacked if else, much cleaner that way.

Also a switch for the other positions.

[Nicholas Jordan]

Code:

else if (iConvert == 9)
{
       Ones = "Nine";
}

coverts to:

Code:

switch( integer numeric value ) 
{
   case 0 : ( code omitted );//
   case 1 : ( code omitted );//
   case 2 : ( code omitted );//
   case 3 : ( code omitted );//
   case 4 : ( code omitted );//
   default: ( code omitted );//
}

You have to place a break; on every statement, or this just becomes something you are not trying to accomplish.
