- Write JAVA code General Problem Description: It is desired to develop a directory application based on the use of a double-linked list data structure, in which students are kept in order according to their student number. In this context, write the Java codes that will meet the requirements given in detail below. Requirements: Create a class named Student to represent students. In the Student class; student number, name and surname and phone numbers for communication are kept. Student's multiple phones number (multiple mobile phones, home phones, etc.) so phone numbers information will be stored in an “ArrayList”. In the Student class; parameterless, taking all parameters and It is sufficient to have 3 constructor methods, including a copy constructor, get/set methods and toString.When constructing structure instances, why should you use the new operator?Computer Science //iterator() creates a new Iterator over this list. It will//initially be referring to the first value in the list, unless the//list is empty, in which case it will be considered both "past start"//and "past end". template <typename ValueType>typename DoublyLinkedList<ValueType>::Iterator DoublyLinkedList<ValueType>::iterator(){//return iterator(head);} //constIterator() creates a new ConstIterator over this list.

- Please just use main.cpp,sequence.cpp and sequence.h. It has provided the sample insert()function. No documentation (commenting) is required for this assignment. This assignment is based on an assignment from "Data Structures and Other Objects Using C++" by Michael Main and Walter Savitch. Use linked lists to implement a Sequence class that stores int values. Specification The specification of the class is below. There are 9 member functions (not counting the big 3) and 2 types to define. The idea behind this class is that there will be an internal iterator, i.e., an iterator that the client cannot access, but that the class itself manages. For example, if we have a Sequence object named s, we would use s.start() to set the iterator to the beginning of the list, and s.advance() to move the iterator to the next node in the list. (I'm making the analogy to iterators as a way to help you understand the point of what we are doing. If trying to think in terms of iterators is confusing,…Movie search system that displays actors and information about the movie. If you search for an actor, it should show you her or his movies. This can be in C++ and must use a data applied structure such as bubble sort or graph wise or using BTS. I would suggest with a BTS type of systemWhat effect does the new operator have when constructing instances of structures?
