scala random number

To generate a random number in Scala, you can use the scala.util.Random class. Here's an example:

import scala.util.Random

val random = new Random()
val randomNumber = random.nextInt()

In this example, we import the scala.util.Random class and create an instance of it called random. Then, we use the nextInt() method to generate a random integer.

If you want to generate a random number within a specific range, you can use the nextInt(n: Int) method, where n is the upper bound (exclusive). For example, to generate a random number between 0 and 9, you can do:

val randomNumberInRange = random.nextInt(10)

This will generate a random number between 0 and 9.

Please note that the scala.util.Random class uses a default random number generator, which may not be suitable for cryptographic purposes. If you need a cryptographically secure random number generator, you should consider using a different library or approach.

I hope this helps!
