Guidelines

Since you're using the java.util.random library, you'll need to first initialize a Random object. Once you've done that, and assuming you are adding your questions to the questions[] array:

You can use the nextInt method to pass in the length of your questions array, so that it returns a random integer between 0 and the length of your array. You can use this as a random index to pull a question, i.e. questions[randomIndex]

I'm linking the docs here as well for you to read over yourself if you need any further information
