Help with java ASAP please
I have to make a program that takes an integer and outprint a string (eg. 247 = two hundred forty seven) for numbers up to 1,000,000,000.
ive gotten this so far need help.
[CODE]
import java.util.Scanner;
/**
This program turns an integer into its English name.
*/
public class IntegerName
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Please enter a positive integer < 1000000000: ");
int input = in.nextInt();
System.out.println(intName(input));
}
/**
Turns a number into its English name.
@param number a positive integer < 1,000
@return the name of the number (e.g. "two hundred seventy four")
*/
public static String intName(int number)
{
int part = number; // The part that still needs to be converted
String name = ""; // The name of the number
if(part >= 10000)
{
name = tensThousandName(part/10000) + " thousand";
part = part % 10000;
}
if(part >= 1000)
{
name = digitName(part/1000) + " thousand";
part = part % 1000;
}
if (part >= 100)
{
name = digitName(part / 100) + " hundred";
part = part % 100;
}
if (part >= 20)
{
name = name + " " + tensName(part);
part = part % 10;
}
if (part >= 10)
{
name = name + " " + teenName(part);
part = 0;
}
if (part > 0)
{
name = name + " " + digitName(part);
}
return name;
}
/**

@param digit an integer between 1 and 9
@return the name of digit ("one" ... "nine")

public static String digitName(int digit)
{
if (digit == 1) { return "one"; }
if (digit == 2) { return "two"; }
if (digit == 3) { return "three"; }

if (digit == 7) { return "seven"; }
if (digit == 8) { return "eight"; }
if (digit == 9) { return "nine"; }
return "";
}
/**

@param number an integer between 10 and 19
@return the name of the given number ("ten" ... "nineteen")

public static String teenName(int number)
{

if (number == 11) { return "eleven"; }
if (number == 12) { return "twelve"; }
if (number == 13) { return "thirteen"; }

if (number == 17) { return "seventeen"; }
if (number == 18) { return "eighteen"; }
if (number == 19) { return "nineteen"; }
return "";
}
/**
Gives the name of the tens part of a number between 20 and 99.
@param number an integer between 20 and 99
@return the name of the tens part of the number ("twenty" ... "ninety")
*/
public static String tensName(int number)
{
if (number >= 90) { return "ninety"; }
if (number >= 80) { return "eighty"; }
if (number >= 70) { return "seventy"; }

if (number >= 40) { return "forty"; }
if (number >= 30) { return "thirty"; }
if (number >= 20) { return "twenty"; }
return "";
}
}
[CODE]
The recommended approach is to rename intName() and create a new intName() with the
same input parameters and return type as the old intName(). The new intName should call the
renamed old intName to convert numbers below 1000 to their word equivalent. Alternatively,
you may use a recursive call to intName(), if you understand recursion. What you definitely
should not do is use multiple copies of the code in intName().
