        System.out.println(myNumbers[i]);
    }
  }
}

Nothing wrong with the code

Loop will through an exception

Array initialization is not correct

Main method cannot be inside a class

Correct Answer

Array initialization is not correct

Explanation

Array is defined to include int values, but it is initialized with string values. An int value does not need to be wrapped with double quotes. The right code will be

public class MyClass {
  public static void main(String[] args) {
    int[] myNumbers = {1, 2, 3, 4};     for (int i = 0; i < myNumbers.length; ++i) {
      System.out.println(myNumbers[i]);
    }
  }
}
