Learning Java from zero

Today I want to share some nice stuff to learn Java with you.

I found a very nice mobile application available online and for Android, IOS and Windows phone, I'm actually following the Java course and I found it very well explained, I recommend it for beginners, I use it when I'm on my way to go to work, I have 4h of train transportation per day so it allows me to spend this time efficiently :)

The application is separated in concepts divided into small subjects each subject into small paragraphs, you have to complete a little quiz at the end of each paragraph and a big quiz at the end of each concept.
You can earn some badges and get a Solo Learn certificate for each course completed.

I also purchased a book: Learn Java the Hard Way from Graham Mitchell which is a really good book for making the first step to learn Java, I wish I had this one when I was studying.
It didn't talk about Object Oriented Programming but it covers the basics in a way that anyone can understand it. Each subject is separated into two: lesson + exercise.

The author statement is that many development books are quite hard to read from start to end for a beginner as they are not written for real beginners, so for him to write a book about learning a language you have to get the point of view of a real beginner and focus on simple things first and learn from zero, instead of going anywhere using APIs...

I personally strongly agree with him and confirm his approach is a very good way to learn Java from the beginning.
For your information, the author is actually writing another book about Object-Oriented Programming.
