The commas and the brackets are a part of the ArrayList class's toString() implementation. If you need your own row representation, either write your own method which does so or better yet, create a...

Use getValues().nextLine().equals("n") instead. The Scanner name is confusing BTW, just name it scanner instead of getValues which is more appropriate for a method name.

You are comparing a Scanner object with a String object.

What's wrong with the getTime() method of the Date class which returns the number of milliseconds elapsed since January 1970 as long? To get the seconds, just divide by 1000.

You can't. The best you can do is perform a copy-on-write if the content to be written is more than the initial capacity with which the array was...

Good luck with the remaining exercises.

Done and done. :-)

Read the contract of the substring method; substring(4, 6) == 2 characters.

Also get in the habit of using uppercase characters for enums i.e. `BIN' instead of `bin'.

Marking this thread as solved since you already started a new thread which is a continuation of this one.
