you have to "hard code it" with use of array for example

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
String[] myArray={"zero", "one", two", "three"};
int num = 0;
System.out.println(myArray[num]);
num = 3;
System.out.println(myArray[num]);
 
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.

As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

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.

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...
