the problem isn´t knowledge, as you know everyone here start from 0 or almost everyone, the problem is that if you have 0 java knowledge you should at least read a bit, or not even read cos you know got a shitload of videos at youtube, you can easily learn the basics there.
but if you dont want to do anything and you want everything to be fixed and you also want to take credits for other ppl work you are not going to learn never.
