By: Suindu De - Suppose we are executing

In this tutorial, i will explain how a number can be converted to its value as a word using Java. If you are wondering how and where this can be used, take the example of Money values. If the Amount is in numbers and you would like to convert the amount in words then this program will be useful for you.
