I do not understand how to do the challenge

Random randomGenerator = new Random(); int randomNumber = randomGenerator.nextInt(facts.length); fact = facts[randomNumber];

RandomTest.java

Use the number ten rather than facts.length.
The facts variable is not defined in the challenge.

Hi Bruce,

I commented the challenge a little:

Random randomGenerator;
// TASK 1
randomGenerator = new Random();

// TASK 2
// int randomNumber = randomGenerator.nextInt(); 
// here the generator will create a rundom number without a range

// TASK3
int randomNumber = randomGenerator.nextInt(10); 
// here the generator will create a rundom number between 0 an 9

String intAsString = Integer.toString(randomNumber);
// create a new String variable and convert the int "randomNumber" into a String using toString method
