I used stringtokenizer, probably overkill, but easier i think to remember than the split method.

Here are the steps for Task about algorithms: 1. User inputs a number which tells us how many numbers will be entered to find the maximum of. This number is not included in the maximum calculation. This number is "N" 2. User enters "N" numbers. 3. You figure out the largest of those numbers. (Hint: the smallest possible int in Java is -2147483648) https://runestone.academy/ns/books/published/apcsareview/VariableBasics/minAndMax.html#:~:text=3.7.-,Integer%20Min%20and%20Max,number%20from%20%2D2147483648%20to%202147483647. You should stick to it, but if you're really stuck: https://textdoc.co/8F7mCz2AwutvqjgD

There's no need to use minimum value of integer (-2147483648). Just check in for loop if it is the first iteration and assign first entered number to the "maximum". Starting from the second iteration just check if other entered numbers is greater than "maximum".

Before attempting the last challenge, I read some of the comments because I was not so sure I followed the requirement. Once I understood what the task was, I actually broke down the task into simple steps. step 1 - make sure I allow a person to enter N number step 2 - if statement to determine if I can proceed etc. It was really challenging but also felt great being able to complete it!!

Okay, what's the point of "display today's date". I literally passed all requirements with: 

        System.out.println("07 07 2021");

I think they meant for us to programmatically display the current date using other classes but with no extra explanation or even explaining how to do it in previous lessons your way is the simplest, yes. You can have a look at the SimpleDateFormat class

You can know the answers of most of the solutions like let's say reverse (3,4,5,6,7) but you don't just System.out.println("7,6,5,4,3") or do you?

I did that exactly with no issues.

I don't understand why in the solution its use arrays, we haven't seen arrays at this point... I was trying with a while loop, but I've had to see another solution... In fact I was not far of the solution.

at the very beginning of the course I had some tasks which were identified as "Epic". But to be honest, they weren´t so mach difficult. The "Task about algorithms"... is not just "Hard", it could easily be specificated as real "Epic" 😸 At this level at least. I sow a few solutions already and spent about 2 days by trying to recognize the way, how this task could be solved... I will try again later 🙄🤦‍♂️

Task about algorithms ... I can't figure it out. I think I will come back to it later. I cannot seem to pass the 5th condition.

Console-based piggy bank was kind of tough for me. It took me longer than anticipated to clear 3 of the verifications. Finished it after 42 tries though. I kept trying to pass it an int and a string separately, but eventually I figured out I would just have to pass string and check if it was equal to sum and if not then parseInt() to change string to int and then add to sum.

Really a tricky one. I have to use "break" two times.

Really great exercises but the explanation can be improved a little bit. I've wasted quite some time figuring out a solution because it was not clear that (the first) N meant the amount of numbers to follow. Nevertheless, great exercises and I know now how to figure out the last one with either an array or without an array. Hint: while and if could be sufficient to fix it when not using an array.
