use a random generated number in 2 methods and call random generator again

I will try to explain this as good as possible. I have 2 methods that both use a number between 1 and 4 generated by a random generator object. I made the random generator object outside both methods but I need to generate a new number, use it in one method and use that same number generated in another method then, generate another number to to the same process. but I cant get how I can Generate a number outside both methods, use it in both methods, and then generate another number to use in both methods. It will be used turn by turn in both methods.
