here is the way with which you can convert any number
fall in to int range of
java primitive . here is a class named
parseInteger inside that a static method is available there
so you can use that static method in your requird place or
i also give a main method in this class which accept a
command line parameter and shows the word value according to it.
i convert the number in indiam number system. means
1432456 = fourteen lacs thirty two thousand fifty six.
and i used Arab and Kharab in place of million and billion and trillion .
i think better you run it and see how it convert number from digits to words.
in the case of any modification required either do yourself or write on javaranch in the same
thread. i will do that for you. probabely when you see the logic behind this , you can easily made your required modifications.
for run this program simple compile by javac and then
run as java ParseInteger 123456
you see the output
One Lacs Twenty Three Thousand Four hundread fifty six.
one more thing i didn't use exception handling mechanism. so if you required do it to made your code more robust. and although the only mistakes that can happened will be at the time of giving input via command line or to static method, so if you take care in both of these concerns , i don't think any exception may occurd ever.
copy this code by cut & paste from the bottom version. i am writing code here in two places one below another. first is formatted that may cause some irritation at the time of
paste but the second one didn't . so if you copy , do it from bottom version.
