For this question we won't be directly working within LinkedList however. Instead, we'll be working with a Runner class:
public class Runner {
private LinkedList firstItemList;
private LinkedList listRemainder;
public Runner() {
firstItemList = null;
listRemainder = null;
}
}
For this question, write a method for the Runner class that will take in a LinkedList, split into two linked lists, and assign their values to firstItemList and listRemainder. Assign firstItemList to be a new LinkedList that just contains the first value. Assign listRemainder to be a new linkedList that contains everything EXCEPT the remainder.
More clearly, if you are given a linked list that looks like: 1 --> 2 --> 3 --> 4 Then assign firstItemList to 1 --> null and listRemainder to `2 --> 3 --> 4``
Please note this will be the only question that deals with a Runner Class instead of the LinkedList class directly.
public void split(LinkedList wholeList) {
}// end split
Solve in JAVA please using LinkedList methods and Node methods only if necessary

The following method will take in a LinkedList as an argument and split it, adding only the first element to the firstItemList and the rest of the elements to listRemainder. The firstItemList and ListRemainder may have to be changed to static in order for the method to be able to access them, or add a setter/getter method for them.

public static void split(LinkedList list) {

firstItemList = new LinkedList();

listRemainder = new LinkedList();

firstItemList.add(list.peek());

list.pop();

listRemainder = list;

}

The complete java code for the Runner class can be defined as follows:

Java Code:

public class Runner<T>//defining a class Runner

{

private LinkedList<T> firstItemList;//defining LinkedList type array variable that is firstItemList

private LinkedList<T> ListRemainder;//defining LinkedList type array variable that is ListRemainder

public Runner()//defining default constructor

{

firstItemList=null;//holding null value in list type variable

ListRemainder=null;//holding null value in list type variable

}

public void split(LinkedList<T> WholeLinkedList)//defining a method split that takes a list in parameter

{

if(WholeLinkedList==null)//defining if block that checks parameter variable value equal to null

return;//using return keyword

firstItemList=WholeLinkedList;//holding parameter variable value in firstItemList

ListRemainder=WholeLinkedList.next;//holding parameter variable next value in ListRemainder

firstItemList.next=null;//holding null value in firstItemList.next element

}

Code Explanation:

Defining a class Runner.
Inside the class two LinkedList type array variable that is "firstItemList, ListRemainder" is declared.
In the next step, a default constructor is defined, in which the above variable is used that holds null value in list type variable.
In the next line, a method "split" is declared in which it accepts "WholeLinkedList" as a parameter.
Inside this, if a conditional block is defined that checks parameter variable value equal to null if it's true it returns nothing.
outside the conditional block, it checks the parameter value and holds value in it.
