# Bouncy Number Program in Java1 min read

In his tutorial, we will learn how to write a java program to check bouncy number. Before we code, let us understand what is a bouncy number.

### Bouncy Number

A number is said to be a bouncy number if the digits of that number are in random order that is not sorted. Example: 121575, 521634, etc.

In other words, a number that is neither an increasing number nor a decreasing number is called a bouncy number.

• Increasing number: The number whose current digit is greater than or equal to the previous digit is called an increasing number. Example: 12345, 45678, etc.
• Decreasing number: The number whose current digit is less than the previous digit is called an decreasing number. Example: 54321, 98765, etc.
