In Java with comments.

Complete Lab11 and 11a.

THEN. use the main method I provided to test your classes. H9.zip

To sort: Sort students, undergrads and grads according to ID. Sort Faculty according to Department and Staff according to Salary.

undergrad.in

graduate.in

staff.in

faculty.in

NOTE: In order to get the 4 points for correctly coding the writeOutput methods, copy these methods within H9.zip (all four) into a word document. Clearly label which is which.

In order to get the 8 points for correctly coding the compareTo methods, copy these methods (all four) into the word document. Clearly label which is which, and upload it here as well as your project. Do not zip it. (zip the project, but upload the word document separately. Just the writeOutput and compareTo methods, please. Thx

H9.zip is below
