Question

Assume a class exists named MyList that has contained in it a data attribute of type MyNode that is named head. The class MyList represents a singly-linked list. In the MyNode class, there is a getter method named getNext() that returns he next node in the linked list. Implement an instance method named print() that takes no formal parameters, returns nothing, and prints out the string representation of each node in the linked list from head to tail, with each node printed on a separate line.

Answer 1

Here is the code for getter

import java.util.*;
class MyNode
{
public int data;
public MyNode next = null;
public MyNode getNext(){
return this.next; // next stores the next node instance.
}
}
public class MyList{
MyNode head =null;
public void print(){
MyNode temp = head; // temp object is to iterate through the list
if(temp!=null){
System.out.println("The data in the linked list are:");
while(temp!=null){
System.out.println("Data in this Node is : "+temp.data);
temp = temp.getNext();
}
}
else{
System.out.println("No data to print");
}
}
   public static void main(String[] args) {
       MyList obj = new MyList();
      
       MyNode node1 = new MyNode();// Node1 is created and assigned.
       node1.data = 10;
      
       obj.head = node1;
       MyNode node2 = new MyNode(); //Node 2 is created and attached to the list
       node2.data = 15;
       node1.next = node2; // node 2 is attached to next field in node 1
      
       obj.print();
   }
}
