Hello!

Random randomGenerator = new Random();

The code above creates a new Random object which is assigned to the randomGenerator variable of the same type. Then it calls .next(number), where number is the highest value the number random can take.

For example, 

Random randomNumberGenerator = new Random();
int randomNumber = randomNumberGenerator.next(150);

// randomNumber will be a number between 0 and 150

Hope it helped!
