Question

There is an array A which outputs the following (without quotations): "Utah", "Texas", "Florida", "Colorado", "Washington".

Write a linked list which stores and access the output from the array A in reverse order and as the user enters the information. Then display the information in any order you like.

Note: take input from the user.

Answer 1

Program:

import java.util.*;

class Program
{
public static void main(String args[])
{
Scanner sc=new Scanner(System.in);

String A[]=new String[5];

System.out.println("\nEnter elements of Array A[]: \n");
for(int i=0;i<A.length;i++)
{
A[i]=sc.next();
}

System.out.println("\nElements of Array A: ");
System.out.println("---------------------------\n");
for(int i=0;i<A.length;i++)
{
System.out.println(A[i]);
}

LinkedList<String> list=new LinkedList<String>();
//Storing elements of Array A[] into LinkedList

for(int i=A.length-1;i>=0;i--)
{
list.add(A[i]);
}

System.out.println("\nStored elements of Linked List:\n");
System.out.println(list);

System.out.println("\n\nUsing Iterator : \n");
Iterator i1=list.iterator();

while(i1.hasNext())
{
System.out.println(i1.next());
}

System.out.print("\n");
}
}

Output:
