Create a helper method
Difficulty: 
One of the benefits of using methods is that we can now create so-called “helper”-methods. A helper method is a method that basically wraps around some existing method, but provides some additional functionality.
In this exercise, we’ll create a helper method for the already existing method readInt that will allow us to read out an integer from the user between certain bounds.
Create the method readIntBetweenBounds(int lowerBound, int upperBound) and make sure it returns a certain value between the provided upper and lower bounds. (You should use a while-loop to do so!)
