Question about the task Number algorithms
Java Core, Level 10, Lesson 10
Under discussion
I decided to dig in and try to understand the code everyone seems to be using to pass this.I am pretty sure that this will pass verification once I change the return to the correct result array. I really wanted to understand what this code did before I used it to pass verification. I dug into it as well as I could and tried to parse out how it was working. I had already written my own cod

Question about the task Implement the print method
Java Syntax, Level 2, Lesson 1
Under discussion
I entered the right solution, but that darn s is throwing me off public static void print(String s) { System.out.println(s); why s, why s, why s? could it just as easily have been some other letter? like: public static void print(String f) { System.out.println(f); It is so strange to me that this wasn't explained.

Question about the task Amigo is very smart
Java Syntax, Level 0, Lesson 2
Under discussion
Amigo is very smart VS Amigo is real smart?How come this did not verify correctly for the output "Amigo is real smart"? According to what im reading for the checks and balances (nr of chars, first word and last word) it should have worked too.

Every single Java course. Why?!Why does every Java course has to include exercises with material unknown to the student? First modulo, now loops. If this continues I'm gonna set up a blog with solutions to those particular tasks.

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.
