Problem 1. [20] Soda Machine. Please write a Java Program (using at least two classes) that steps through the process of buying a soda from a Soda Machine. You must interact with the consumer. Each Soda is one dollar. You can assume the soda machine is always full of your favorite sodas. Your machine takes in only 1 and 5 dollar bills. Your machine calculates change. Critical Thinking: Rework on the above problem if you change the assumption as your machine may run out of your favorite sodas and it can takes in 1, 5, and 10 dollar bills.
