Hi @Nguyễn Việt Thiện,
I can see you changed the original question. It would be better if you can create another topic and we can discuss more
And if you want to learn Java, I would also suggest you learn a few things first:
- Learn to be honest. Lies don’t bring you anywhere.
- Learn to be humble. You are still at the starting point, so if you represent yourself as a boss and ask people to do your homework for you like the following statement, then I can tell you your future even I am not a fortune teller.
- Start working hard. There is no easy way to learn anything without spending time and effort on it, so you can stop finding a quick way to learn something (in fact, you are not learning, you are trying to find the way to cheat). Eventually, you will know that those “easy ways” bring you nothing.
- Stop cheating. Go to a platform and ask some so-called experts to do your homework for you doesn’t bring you knowledge, or sharp your skills.
And also, they are not experts at all. Their code sucks.
I hope you remember that your choice in every moment will shape you in the future. So, please choose wisely
