How to Reverse a Number in Java

In this post we’ll see how to reverse a number in Java. The Java program to reverse a number can be written in both iterative as well as recursive way. Both solutions are given here.
Logic for both of the method is similar; you need to do a modulo division by 10 to get the last digit and using that remainder you need to create the reversed number. In iterative method this will be done in a loop where as in a recursive method you will call the method again after removing the last digit.
