Your first 2 errors appear to indicate that you did not import the Scanner class. The rest are related to inconsistencies in your code, like:

It's not clear how the 4 parts you posted go together. Are they each stand-alone parts, saved in their own files? If so, there are missing braces, { or }. If not, describe how the parts fit together.

The second bit of code you posted makes no sense. It begins with a constructor, Student2(), but there's no class Student2.

Help us understand what's going on here.
