No Java anywhere, it will be too difficult. There should be a lot to read docks, as the blogs don't share everything and some information is outdated, written during version 4, if not sooner. Well a lot of frills used.
Well to start with the book of Shilda Java 8 complete guide. I read about 7, but it doesn't matter. He is very detailed and reveals all the details, after which everything becomes clear. You need to read at least about the basics: syntax, operators, OOP.
If this is the first language to be quite difficult. The difficulty lies in the ability to create a comfortable architecture with efficient algorithms.
