I have two very seperated questions

What is the main method supposed to do?I can tell I'm misunderstanding how the program is supposed to work, since I am only printing out "Interrupted!" instead of actually calling the interrupt() method, but I don't understand what the main method should do and what the purpose is of the main method calling Thread.sleep(3500)

What is wrong with my code?No idea why I fail the test. I saw the solution but it doesn't make any sense. 1) they do not close the stream 2) And I don't see what is wrong with my code as the only difference is that they add if(total != 0;

Appreciate a another set of eyes. Not sure why it is failing. I often would rather stare at the code until I see the issue, but this one it taking me too long. It is complaining that: The Solution class must have two methods.

Java Core, Level 10, Lesson 2

Hmm, Missing something here.It seems like it is a fairly straight forward task, but there is something I am missing. It keeps telling me that: "Check why the users list is empty after the file has been read." I figure it is some super obvious thing that I am simply not seeing.

hi there! I've got the idea what to do but little confuse if the position of lines of file1 are different as that of the file2, then that line will be considered as removed? for example : //list1.get(0).equals(list2.get(4)) the element in this case will be encountered with what tag ? Same, Removed,Added?
