Hi guys i am new here
i want to help about:
how to convert digit(number) into word
for example:
Enter a number:123
Output:one hundred twenty-three
peter_budo 2,516
you have to "hard code it" with use of array for example
String[] myArray={"zero", "one", two", "three"};
int num = 0;
System.out.println(myArray[num]);
num = 3;
System.out.println(myArray[num]);first return will be string zero and second one will be three

which won't provide a correct solution in almost any situation :)
You'll need a lot more logic than that, but it could be used as a starting point.
Instead of an array though you should really consider using an enum.

This is going to be harder than you think due to the fact that numbers are represented differently depending on the position in the number the specific digit is in. For example, if a 5 is in the one's slot, it is represented as "five", whereas in the ten's spot it is fifty-[ones digit number(unless zero)], then back to "five" for the hundreds and so on.
In a nutshell, you would need a fair amount of logic as jwenting stated, just figured I would elaborate some more.

I would approach this making an ArrayList of strings instead of a list (tad more versitile, but list of Strings will do as well) and then create a string variable that you can do x = x + number.toString();
Perhaps some if statements will solve the other have of the problem ;)
if (number ==1) then list.get(n-1);

How so? An ArrayList is a List, unless you mean to use ArrayList instead of an array of Strings.
I mis spoke... I had some python crossing my java and things were fuzzy... but you are right... Array List instead of an Array of strings..
How do I convert the Integer to String by:
1. Asking the user to input the number (Eg: 704 = Seven Hundred and Four)
2. Display the output in JTextArea.
Thanks for your support.

Start a new thread. This is a 3 year old thread.

HIYA GUYS
VERY BASIC WAY OF DOING IT AND ONLY HANDLES UP TO NUMBER 999 ALTHOUGH CAN BE ALTERED PRETTY EASILY.
THIS CODE DOES NOT USE CONFUSING ARRAYS WHICH WOULD CUT DOWN MY CODE A LOT BUT THIS CODE IS THE FULL WHACK AND THE WAY THEY WOULD TEACH SOMEONE AT UNIVERSITY AT BASIC LEVEL.
COPY AND PASTE INTO JAVA EDITOR...
OBVIOUSLY A GOOD WAY TO UNDERSTAND MY CODE PROPERLY OR ANY CODE IS TO USE THE DEBUG OPTION IN UR JAVA EDITOR TO GO THROUGH THE STEPS ONE BY ONE FOR ANY GIVEN NUMBER
THANKS BYE...

Inspired by the above response, I've coded a complete method that covers all values of integer numbers in Java (from Long.MIN_VALUE to Long.MAX_VALUE). Done in 100 lines ;)
For example, calling numberInWords(Long.MAX_VALUE) will print out:

/** Holds the tens places **/
private static final String[] TENS = {"ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninty"};
/** Covers max value of Long **/
private static final String[] THOUSANDS = {"", "thousand", "million", "billion", "trillion", "quadrillion", "quintillion", "sextillion"};

plz help.how we convert negetive number into negetive world.for example-123 into negetive one hundred twenty three

What do you mean by that? If you can see it then what is the problem?
To >> ss999
This thread already has sample code for the conversion.
Here is a class file for converting Number to Word.
Download Class file
For example:
E:\Java_practical>java n2w
___________________________________
Enter an amount: 121
---------------------------------
The amount you entered in words is
one hundred and twenty one only
___________________________________E:\Java_practical>java n2w
___________________________________
Enter an amount: -121
---------------------------------
The amount you entered in words is
Negative one hundred and twenty one only
___________________________________E:\Java_practical>java n2w
___________________________________
Enter an amount: 2007483613
---------------------------------
The amount you entered in words is
two hundred crore seventy four lakh eighty three thousand six hundred and thirteen only
___________________________________
Input range: -2147483647 to 2147483647.
(without exception handling for 'string input' and 'input above the range').
I'm new for java. Here i used 'if else if', 'switch'& 'while'. Maybe some easy ways available for conversion.
The source code is about 241 lines with neat structure(My first java program:)).

Dude all the code is directly above, are you blind>?
Hi,
no need to hard code, just download bussinessapi.jar and add this jar file to your project. then write this code:
double array[] = { 100.22,13 };
AmountByWord amountByWord=new AmountByWord();
amountByWord.setLanguage( "en" );
amountByWord.setCurrency("IN");
for (int i = 0; i < array.length; i++)
{
try {
System.out.println( amountByWord.getMoneyAmountByWord( array[ i ] ) );
} catch ( Exception e ) {
e.printStackTrace();
}
System.out.println( "---------------------------------" );

1) You just replied to old thread
2) You did not use code tags
3) You recommend to use old deprecated API
what can I say BAD, BAD, BAD for all 3

davidlad: what did you think peter_budo meant by the above post? this thread is five years old. just because some people seem to need to revive it now and then, doesn't mean it's the right thing to do.
the chances of the OP still looking for a solution for this are pretty small, wouldn't you agree?
