Program :-(How to find out nth value by using array in Java?)

import java.util.*;
class value
{
Scanner sc=new Scanner(System.in);
int pos;
public void search(int n)
{

int arr[]=new int[n];
System.out.println("Enter Elements of Array :");
for(int i=0;i<n;i++)
{
arr[i]=sc.nextInt();
}
System.out.print("Array is :");
for(int i=0;i<n;i++)
{
System.out.print(arr[i]+" ");

}
System.out.println("\nEnter The Position of Element you want to Print :");
pos=sc.nextInt();
if(pos<0 || pos>n)
{
System.out.println("Position out of Range :");
}
else
{
System.out.println("Element at that position is :"+arr[pos]);
}
}
public static void main(String args[])
{
Scanner s=new Scanner(System.in);
System.out.println("Enter How many Elements you want to Store :");
int no=s.nextInt();
value v=new value();
