Question: Create a class Listnode which has two private data fields: data (int type) and next (Listnode type). The class should have a constructor which initializes the value of data. Additionally, the class should have accessor and mutator methods for both data fields.
package additional_problems.linkedList;
/**
* This class is the type declaration for a linked list
* Created by aarushi on 24/6/21.
*/
public class ListNode {
//data fields
private int data; //stores the value of the node
private ListNode next; //stores the reference of the next node
//constructor to initialize the value of the node
public ListNode(int data){
this.data= data;
}
//accessor method to get the value stored in data
public int getData() {
return this.data;
}
//mutator method to change the value of data
public void setData(int data) {
this.data = data;
}
//accessor method which returns the reference of the next node
public ListNode getNext() {
return this.next;
}
//mutator method which changes the reference of the next node
public void setNext(ListNode next) {
this.next = next;
}
}
