Using java

a.Create an array of 15 student records that should not be sorted.

b.Create a liked list of 15 student record nodes. Each node is a node of one student record from the above unsorted array. The list of student records should be sorted by student ID. (Insert function without sort function to create a linked list.)(If you insert correctly, the resulting linked list is sorted.)

c.Each student record consists of student ID, student name, Student address, and GPA.

d.The student records must be defined as student object class with member functions. (No class definition declaration will be no credit for the project.)

e.Turn in source programs and Execution output:

1.Display the student records from the unsorted array

2. Display the student records from the linked list. (Display function) The output of the linked list should be sorted by using insert function from beginning of the list. Do not use SORT Program. Using it will get penalty.

3. Delete the kth record from the middle of the sorted list and display the resulting list. (Delete function.)

4. Insert a mth record to the middle and display the resulting sorted list. (You decide the kth and mth with proper message.)

f.You can not use the high level STL library or functions such as container classes or container adapter classes if you know how to use them (section 17.1 in ninth edition.) If you do not know, just ignore this statement.

Please just add on to what I already have.

This is what I have so far. It is not sorted (step b) and i'm confused on step 2, 3, and 4.
