Getting NZEC runtime error for using Scanner to take input in Java

,
1

How to fix this? Getting the correct answer when I do custom input but showing error when I try to submit

2

It is better to use try-catch blocks in exception handling to avoid this error.

3

Can you please elaborate further? Like how to take the input if I want to?

If you want to take input you can follow the below syntax by using try-catch blocks.
`import java. util.*;
public class Main {
public static void main(String[] args) {
try
{
Scanner sc =new Scanner(System.in);

        // You can write your code below without getting the NZEC error by using try-catch blocks(Exception Handling).
        
        
    } 
    catch (Exception e) 
    {
        return;
    }
         
}

}`
