Question

The object class should be a Student with the following attributes:

id: integer

first name: String

last name: String

write the accessors, mutators, constructor, and toString().

In your main test class you will write your main method and do the following things:

Create an array of Student objects with at least 5 students in your array.

Write a sort method that must be your original work and included in the main class. The sort

method will sort based on student id.

Output the array out in unsorted order as it exists.

Sort the array

Output the sorted array
