Taking input of the Linked List inputs and size

#1

How to take input of the size of the linked list and ist nodes one by one on the output screen. Please explain a complete programme where we build a linked list by reading its inputs from the keyboard

#2

you need to write a class , say class name is Node.
class Node
{
int data;
Node next;
Node(int data)
{
data=data;
next=null;
}
}

now this class represents nodes of linked list.
your next task is to take inputs and create a node of each input and attach them(link them ) to form a linked list.

what if we don’t know no of inputs? you can take undefined no of inputs in following way:
I am attaching code for taking dynamic number of inputs and forming a linked list:

import java.util.*;
public class Test{
private class Node
{
int data;
Node next;
Node(int data)
{
this.data=data;
this.next=null;
}
public void print(){
System.out.println(“value is:” + data);
}
}
public void display(Node head){
while(head!=null){
head.print();
head = head.next;
}
}
public static void main(String[] args){
Test obj = new Test();
Scanner s = new Scanner(System.in);
String input;
Node head = null, curr=null, newNode=null;
try{
while(!(input = s.next()).equals("")){
newNode = obj.new Node(Integer.parseInt(input));
if(head == null){
head = newNode;
}
else{
curr.next = newNode;
}
curr = newNode;
}
}
catch(Exception ex){
System.out.println(“Done with input”);
}
obj.display(head);
}
}
