Numeric Value to String representation

Question

Hi!
I was wondering if there was an easy way to getting the String representation of a number (specifically an integer). I am trying to format a message that would be like this:
Three (3) records have been updated.
Getting the (3) is easy, but my problem is getting the word Three. There are numerous records, which means an Array would be close to impossible coz it will take time to produce an output.
Is there an easy way? (1 = One, 2 = Two,..., 20 = Twenty)
Thanks!

I'd guess that a switch statement will be about as fast as anything else, since it's a static structure and the compiler should be able to optimize it effectively.
int number = setMeToAValue;
switch (number) {
    case 0:  System.out.println("zero"); break;
    case 1:  System.out.println("one"); break;
    case 2:  System.out.println("two"); break;
    case 3:  System.out.println("three"); break;
    case 4:  System.out.println("four"); break;
    case 5:  System.out.println("five"); break;
    case 6:  System.out.println("six"); break;
    case 7:  System.out.println("seven"); break;
    case 8:  System.out.println("eight"); break;
    case 9:  System.out.println("nine"); break;
    case 10: System.out.println("ten"); break;
    case 11: System.out.println("eleven"); break;
    case 12: System.out.println("twelve"); break;
    case 19  System.out.println("nineteen"); break;
    case 20  System.out.println("twenty"); break;
    case 30  System.out.println("thirty"); break;
    case 40  System.out.println("forty"); break;
To get 21 go after the parts and concantenate them. case 20 + case 1 produces 21, etc
