Question

I want to implement a linked list using java language

the node class

the SingleLinked class

And here is the linked list class

Explanation / Answer

/* * Java Program to Implement Singly Linked List */ import java.util.Scanner; /* Class Node */ class Node { protected int data; protected Node link; /* Constructor */ public Node() { link = null; data = 0; } /* Constructor */ public Node(int d,Node n) { data = d; link = n; } /* Function to set link to next Node */ public void setLink(Node n) { link = n; } /* Function to set data to current Node */ public void setData(int d) { data = d; } /* Function to get link to next node */ public Node getLink() { return link; } /* Function to get data from current Node */ public int getData() { return data; } } /* Class linkedList */ class linkedList { protected Node start; protected Node end ; public int size ; /* Constructor */ public linkedList() { start = null; end = null; size = 0; } /* Function to check if list is empty */ public boolean isEmpty() { return start == null; } /* Function to get size of list */ public int getSize() { return size; } /* Function to insert an element at begining */ public void insertAtStart(int val) { Node nptr = new Node(val, null); size++ ; if(start == null) { start = nptr; end = start; } else { nptr.setLink(start); start = nptr; } } /* Function to insert an element at end */ public void insertAtEnd(int val) { Node nptr = new Node(val,null); size++ ; if(start == null) { start = nptr; end = start; } else { end.setLink(nptr); end = nptr; } } /* Function to insert an element at position */ public void insertAtPos(int val , int pos) { Node nptr = new Node(val, null); Node ptr = start; pos = pos - 1 ; for (int i = 1; i list.getSize() ) System.out.println("Invalid position "); else list.deleteAtPos(p); break; case 5 : System.out.println("Empty status = "+ list.isEmpty()); break; case 6 : System.out.println("Size = "+ list.getSize() +" "); break; default : System.out.println("Wrong Entry "); break; } /* Display List */ list.display(); System.out.println(" Do you want to continue (Type y or n) "); ch = scan.next().charAt(0); } while (ch == 'Y'|| ch == 'y'); } }
