Get specific digits of random number in Java

This post is about getting specific number of digits of random numbers in Java. We will be using the Random API from Java for this.

Let’s assume we want 5 random integers from 0 to a 1000. Then, we will use the following code snippet:

String randomNumberString = String.format("%05d", new Random().nextInt(10000));

As it can be seen, we have used String.format to give us the specific number of digits.
