Hi Jamar, 

Random randomGenerator = new Random();

Here we are generating a new Random number object and storing it in a Random object called randomGenerator.

int RandomNumber = randomGenerator.nextInt(10);

getting a random number by calling the nextInt method on randomGenerator, which we know is an object of type Random. the parameter we are passing in the method is the upper bound of what the number can be. So in this case it can be between one and ten. Finally we are storing this random number into a variable called RandomNumber (this should probably be randomNumber) which is of type int.

The next thing to do would be to call ToString() on randomNumber and store it in a string variable.

string intAs = randomNumber.ToString();
