Where/how can I learn Java?

Hello, first of all this is my first post and I hope i'm posting this in the right place!
I know this question must of been answered tons of times so sorry

I am completely new to learning, I don't know any languages.
but i am looking to learning java as i want to start developing plugins for my future server.
so i have some questions that you hopefully help me out on!

1: Wheres the best place to learn java? even if its a book?
2: how much java will i need to learn for plugins? sure i would love to know tons of java, but for now i just want to know as much that will let me build plugins.

and 3: how long will this learning process take? i will be learning 24 7 as i have no life lol...

thanks for taking your valuable time in answering my Questions and also, im pretty stupid in learning so will it be hard for me to learn? thnx!

 

@Kawaii_Kat17
I liked Java For Dummies. But thenewboston is a great YouTube channel in my opinion.

 

@timtower @Halmerson thank you both for your help, i chose to watch Derek Banas as it looks like he has heaps of tutorials. also how much java will i need to learn to make plugins? learning heaps would be good, but i only would be using Java to make plugins so i dont think ill need to know tons? right?

 

Oh my, might be worth learning tons of java then well thanks for you help! its really appreciated

 

Just don't jump, so don't go straight learning hiw constructors work, just because it's in the list

 

@mcdorli Ive bought a book for my ipad lol, the book is "java for dummies all in one" it has 9 books in one and did cost me alot so im hoping i can learn from this and not from youtube videos

 

This free book looks pretty good: http://greenteapress.com/thinkjava6/thinkjava.pdf
I actually have a bookmark folder full with links to Java tutorials / books, if you want more, just poke me about it

 

Oh thanks Ill definitely check that out also!

 

The ."... for dummies" are pretty good, yeah
