Java Exceptions Practice 56.2 Category Handling Fails Test Case 4

Question

I am having trouble with Java Exceptions Practice 56.2 Category Handling

It is supposed to catch exceptions and output: "Wrong Option"

I have tried a generic catch (exception e), I have also tried to catch NoSuchElementException instead of catching InputMismatchException

I also tried just letting it throw an InputMismatchException on a non-integer input.

I haven't been able to think of any test cases I didn't try in my IDE.

import java.util.InputMismatchException;
import java.util.Scanner;
//fails test case 4
public class Main
{
public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

String[] categories = {"PCs", "Notebooks", "Tablets", "Phones", "Accessories"};

try {
int choice = scanner.nextInt();
System.out.println(categories[choice]);
} catch(ArrayIndexOutOfBoundsException | InputMismatchException e) {
System.out.println("Wrong Option");
}
}
}

Answer 1

In the text : "Use the Exception type to catch all possible exceptions."
So just use Exception class to catch exception
=> catch (Exception e) { ... }

I have tried with ArrayIndexOutOfBoundsException, it works too

test case 4 should print Accessories, check spelling in your code.

Answer 2

Yes, the problem was the "А" in "Аccessories" is Unicode \u0410 Cyrillic Capital Letter А in the provided code, instead of \u0041 Latin Capital Letter A.

My code worked just fine as soon as I replaced A with А.

The provided code will not catch a non-integer input (such as "A") as written, even with

catch (Exception e)

because

int choice = scanner.nextInt();

is not in the try block, but there are no test cases with non-integer input.
