Write a java code : Student ID at University is composed of year of admission and students number. we aim to implement a structure that improves operations of inserting and searching for a student. To enhance these operations, we will build a tree of linked lists (TreeOfLists) to combine advantages of both structures. Each node in this tree contains a linked list of all students who were admitted in that year. Each node in the linked list represents a student(id,...
