This is the situation
You’ve been hired by the local Lottery Agency to create a program that automatically picks one set of six random numbers.
The first five numbers must be unique whole numbers (no duplicates), and each of them must be greater than 0 and less than 51. The sixth number can be any whole number greater than 0 and less than 61.
After displaying the first set of six numbers, the customer should be asked if he or she would like another set of numbers. Continue to display a set of numbers as described above, as long as the customer answers “yes”. Otherwise, end the program.
Your solution must be separated into, at least, two files (Implementation class and a Test class). There should only be minimal code in the Test class, just enough to instantiate an object, and invoke the appropriate function(s).
