Problem & Solution
The demand is easy, while I had no idea about the way of encapsulation for the lack of experience. Our aim is to calculate all the prime from 1 to N, so it should be written as a method. So I new a class called 'Prime'. When I initialise the variable in the class, it turned out error. The assistant professor told me that all the operations should be written in Constructor or Method. Then I put the initialization in the Constructor. Problem solved!
