Question about the task Fixing bugs
Java Core, Level 3, Lesson 11
Under discussion
Just looking for some explanation about what the code is doing I had no problem passing the validation (IDEA makes it easy by underlining errors) so there's no attached code here. I just want to ask for some clarification about what the code is doing in this task. Why does the interface create an object of the class that implements it? Is this normal practice?

Question about the task Catching unchecked exceptions
Java Syntax, Level 9, Lesson 8
Under discussion
If you're stuck, look at RuntimeException This task puzzled me for a while. You need to... In the handleExceptions method, handle all unchecked exceptions. You can only use one try-catch block. If you're stuck, know that NullPointerException, IndexOutOfBoundsException and NumberFormatException are all subclasses of RuntimeException.
