Assignment: Linked List In this problem you are going to implement a single linked list of students. A linked list is composed of nodes. So first of all, you need a StudentNode class. Each student node should hold his name and ID. In addition to that, each node must hold a pointer or reference to the next node in the list, because this is a linked list and not a simple array The StudentList would hold only a reference to the first node in the list, also known as the head. From this node, we can start traversing the list of students by following the next pointers in each student node. The list also has the following methods: . isEmpty(): returns true if the list does not have any node .addFirst(): adds a new StudentNode to the start of the list. .addLast(): adds a new StudentNode to the end of the list. . print(): print the list by calling toString() for each node getID(): given the name of a student, search in the list, and return his/her ID. . removeNode(): given the name of a student, search in the list, and remove it. . removeAll(): delete all nodes from the list. . reverse: reverse the whole list order by making the first node become the last and vice versa (and everything in between) StudentNode StudentList head: StudentNode name String - ID int next: StudentNode StudentList () +isEmpty (): boolean +addFirst (node StudentNode) +addLast (node: StudentNode) + print () void +getlD (name String): int +removeNode (name String) boolean + removeAll () +reverse () + StudentNode (name String, ID int) // setters & getters +toString) String Write a tester class in which you initialize a StudentList object. Read 4 student names and IDs from the scanner. Add the first one using addLast(), the second one using addFirst(), the third and fourth one using addLast() 1. 2. Print the entire list using print() 3. Call getID("john") and print its result. hold his name and ID.

Read 4 student names and IDs from the scanner. Add the first one using addLast(), the second one using addFirst(), the third and fourth one using addLast() 2. Print the entire list using print() 3. Call getID("john") and print its result. 4. Call removeNode("john'") 5. Print the entire list using print(). 6. Call isEmpty() and print its result. 7. Call removeAll() 8. Call isEmpty() and print its result.
