How do you reverse a number in Java?

Example 1: Reverse a Number using a while loop in Java

  1. First, the remainder of the num divided by 10 is stored in the variable digit.
  2. After second iteration, digit equals 3, reversed equals 4 * 10 + 3 = 43 and num = 12.
  3. After third iteration, digit equals 2, reversed equals 43 * 10 + 2 = 432 and num = 1.
