The error message you're seeing is a `NoSuchElementException`. This exception is thrown by the `Scanner` class when you're trying to read an element that doesn't exist.

Here's a step-by-step explanation of the error:

1. You're using the `Scanner` class to read input. This class is often used to read user input from the console.

2. The `nextInt()` method is being called on the `Scanner` object. This method reads the next token from the input as an `int`.

3. However, there's no next token that can be read as an `int`. This could be because the input is empty, or the next token cannot be interpreted as an `int`.

4. As a result, the `NoSuchElementException` is thrown.

To fix this error, you need to ensure that there's an `int` to read when you call `nextInt()`. You can do this by checking if there's a next `int` using the `hasNextInt()` method:

```java
Scanner scanner = new Scanner(System.in);
if (scanner.hasNextInt()) {
int number = scanner.nextInt();
} else {
System.out.println("No integer input provided");
}
```

This code will only call `nextInt()` if there's an `int` to read, preventing the `NoSuchElementException`.
