How do we ensure the alteration of labels properly?This is quite an interesting task, actually. I'm supposed to create a list that merges lines from two files: the original one and its updated version. The lines should be preceded by suitable labels: SAME, REMOVED OR ADDED.

Question about the task Even characters
Java Core, Level 9, Lesson 5
Resolved
Can't pass the 2nd requirement even with an explicit close() statement. I tried it without a catch block and with one. And also added an explicit close statement (not needed) in this try-with-resources block in my last attempt. The 2nd requirement just won't give me a pass. What is the catch here? It annoys the hell out of me. I learned from the web that in a program

I believe this task should be clarified Hello all, The condition listed for passing this check isn't as clear as it should be; the example that is listed only has you place the first and second row's interior characters with the hyphen. However, the passing solution wants you to replace every interior character with a hyphen. This is wh

The first one creates two lists, one with keys and one with values. You can see that version in comments. The second variant uses a HashMap instead (which, obviously, has keys and values). That is the main co
