Question

Really my Turkish instructor has problems with communicating the material. He likes drawing children's pictures I need some help in uderstanding this linked ds method. Here are the instructions. In the code below only the section for the method can be made and altered.(IN BOLD) I am providing the List and Tester class codes.

Here is the List.java to create the method..

public class List {

private class Node {
private int data;
private Node next;
public Node(int d, Node nodePar){
data = d;
next = nodePar;
}
}

private Node head;

public List(){
head = null;
}
// Do not modify any code above this line.



// Write createListForProject3 method here.



public static void displayMyName(){
System.out.println("Programmed by name. ");
}

public void addToHead(int dataPar){
head = new Node(dataPar, head);
}

public void displayList(){
Node tmp = head;
while(tmp != null){
System.out.print(tmp.data+ " ");
tmp = tmp.next;
}
System.out.println();
}
}

Here is the Tester.Java to test the program.

public class Tester {
public static void main(String[] args) {
List.displayMyName();
List list1 = new List();
list1.addToHead(8);
list1.addToHead(20);
list1.addToHead(6);
list1.addToHead(4);
list1.addToHead(50);
list1.addToHead(2);
list1.displayList();
List list2 = list1.createListForProject3();
list1.displayList();
list2.displayList();
System.out.println("Good Bye..");
}
}

Here is what the final code should look like:

Explanation / Answer

//requested function

// Write createListForProject3 method here.
public List createListForProject3(){
Node tmp = head;
List Result = new List();
  
while(tmp != null){
if (tmp.data % 10 != 0)
Result.addToHead(tmp.data);
tmp = tmp.next;
}
return Result;
}

// full code

public class List {
private class Node {
private int data;
private Node next;
public Node(int d, Node nodePar){
data = d;
next = nodePar;
}
}

private Node head;

public List(){
head = null;
}
// Do not modify any code above this line.

// Write createListForProject3 method here.
public List createListForProject3(){
Node tmp = head;
List Result = new List();
  
while(tmp != null){
if (tmp.data % 10 != 0)
Result.addToHead(tmp.data);
tmp = tmp.next;
}
return Result;
}

public static void displayMyName(){
System.out.println("Programmed by name. ");
}

public void addToHead(int dataPar){
head = new Node(dataPar, head);
}

public void displayList(){
Node tmp = head;
while(tmp != null){
System.out.print(tmp.data+ " ");
tmp = tmp.next;
}
System.out.println();
}
  
public static void main(String[] args) {
List.displayMyName();
List list1 = new List();
list1.addToHead(8);
list1.addToHead(20);
list1.addToHead(6);
list1.addToHead(4);
list1.addToHead(50);
list1.addToHead(2);
list1.displayList();
List list2 = list1.createListForProject3();
list1.displayList();
list2.displayList();
System.out.println("Good Bye..");
}
}
