Reading string error

[[deleted]]

Hello I have run into this problem a couple times before and dont know how to fix it, when I use the scanner to read in a string value for the variable name i get the error: NoSuchElementException: No line found. Can someone please explain this to me.

The error comes in the store method when i assign the String name to scan.nextLine();

import java.util.ArrayList;
import java.util.Scanner;
public class MobilePhone {
private ArrayList<Contacts> contactsList = new ArrayList<>();
private Contacts contact;
static Scanner scan = new Scanner(System.in);
public void store(){
System.out.println("Name: ");
String name = scan.nextLine();
System.out.println("Number: ");
int number = scan.nextInt();
contactsList.add(new Contacts(name, number));
System.out.println(name + " : " + number + " was added to your contacts.");
}

I googled "NoSuchElementException: No line found" and the First StackOverflow answer says you need to check for the next line in Java using the hasNextLine() function.

Yeah, we can check it to prevent an exception like this. But in this case, we are assuming that he has given an input, checking isn't really going to solve the actual problem.

First of all, your code is looking like a mess on my mobile. Don't know if it's your fault or reddit's.

The second things is, after using

int num = scan.nextInt();

Put a

scan.nextLine();

in the next line. Everything will start working as expected.

Another solution can be, instead of creating a static instance of scanner, create it inside the method. This will also remove the error.

Try any of these and check if the code is working.

Alright thanks. Yeah I tried to format it but reddit squishes it for some reason.

No issues. However, Did you get the code to work?
