| Which data structure to use? Suppose you need to store a list of elements, if the number of elements in the program is fixed, what data structure should you use? (array, ArrayList, or LinkedList) If you have to add or delete the elements at the beginning of a list, should you use ArrayList or LinkedList? If most of operations on a list involve retrieving an element at a given index, should you use ArrayList or LinkedList?
Java - Elements in a Range
Create class Test in a file named Test.java. This class contains a main program that performs the following actions: Instantiate a doubly linked list. Insert strings “a”, “b”, and “c” at the head of the list using three Insert() operations. The state of the list is now [“c”, “b”, “a”]. Set the current element to the second-to-last element with a call to Tail() followed by a call to Previous()Then insert string “d”. The state of the list is now [“c”, “d”, “b”, “a”]. Set the current element to past-the-end with a call to Tail() followed by a call to Next(). Then insert string “e”. The state of the list is now [“c”, “d”, “b”, “a”, “e”] . Print the list with a call to Print() and verify that the state of the list is correct.
Complete the method “readdata”. In this method you are to read in at least 10 sets of student data into a linked list. The data to read in is: student id number, name, major (CIS or Math) and student GPA. You will enter data of your choice. You will need a loop to continue entering data until the user wishes to stop. Complete the method “printdata”. In this method, you are to print all of the data that was entered into the linked list in the method readdata. Complete the method “printstats”. In this method, you are to search the linked list and print the following: List of student’s id and names who are CIS majors List of student’s id and names who are Math majors List of student’s names along with their gpa who are honor students (gpa 3.5 or greater) All information for the CIS student with the highest gpa (you may assume that different gpa values have been entered for all students) CODE (student_list.java) You MUST use this code: package student_list;import…
