Scanner In Java

I'm trying to write a basic java program so that when I run it, I can store the names and codes of some of my school textbooks...I try the scanner statement to input the name of the book but an exception is thrown when I type the name of the book..I have attached the code for my program.

import java.util.Scanner;
public class Books{
public static void main(String[] args) {
Scanner s=new Scanner(System.in);
System.out.print("Enter amount of products : ");
int products= s.nextInt();
long [] code= new long[products];
String[] names = new String[products];
for (int x=1;x<(products+1);x++){
System.out.println("Enter IMEI number "+x);
code[x] = s.nextLong();
System.out.println("Enter name "+x);

[code]....
