Try below, and choose the "currency" in the pulldown menus inside the JAVA box:

and remember, this is no "s" following Thousand, Hundred etc.

I used to write a program in "C++" for changing the numbers into currency, and quite complicated and need to use "recursive" algorithm and easily lead to an infinity loop and hang the PC.

Actually, don't be scaried by the numbers, there is a way by the American that by adding commas:
$145452.96 -> $145,452.96
So the number is divided into 3 parts and it is simple if u spell the numbers:
a) 145   -> One Hundred Forty Five
b) 452   -> Four Hundred Fifty Two
c) .96    -> Ninety Six

a) is in the "Thousand", and c) is in the Cents level, so you just join them together:
One Hundred Forty Five THOUSAND Four Hundred Fifty Two and Ninety Six Cents.

There is no any "s" after THOUSAND etc.

So, try another group $123145452.96 -> $123,145,452.96
a) 123 -> One hundred twenty three (Million)
b) 145 -> One Hundred forty five (Thousand)
c) 452 -> Four hundred fifty two
d) .96 -> Ninety Six

Again by joining together, you will get
One hundred twenty three Million One Hundred forty five Thousand Four hundred fifty two And Ninety Six Cents

It's one of the algorithm to be used to decide the "million", "thousand" etc level in a computer program. And so now u should know why the American like to put "commas" in the numbers.
