Generating random numbers to deploy a sub

We need to deploy a sub' in a random position at the start of each game. There are, however, many possible uses for random numbers as we will see throughout this book. So, let's take a close look at the Random class and one of its methods nextInt.

The Random class and the nextInt method

Let's have a look at how we can create random numbers and later in the chapter we will put it to practical use to spawn our sub'. All the demanding work is done for us by the Random class.

Note

The Random class is part of the Java API which is why there is a slightly different import statement to get access to it. Here is the line we added in chapter two.

import java.util.Random;

Note that this is the only import statement (so far) that starts with java… instead of android….

First, we need to create and initialize an object of type Random. We can do so like this:

Random randGenerator = new Random();

Then we use our new object's nextInt...
