Try to start with Java Tutorial (from java.sun.com) or with Thinking in Java book, which is free and you can find it on the internet.

Anyway, 1-2 days is a killer deadline for that kind of task ... But your boss just have to know that you succeeded in learning java :) And you will master the language in time...

I beleive you can learn java in a day with great desperation provided you have knowledge in any other programming language. Your nearest source is to search for a tutorial on internet. However, you will need a book to support. Usually, most java programmers often refer to books. "Java: How to Program" by Dietel and Dietel is a good book.

The Java language is a relatively small thing to learn in comparison to the APIs, especially if you already have a good grasp on a similar language. It is good to always have the API reference handy, so you may want to download that: http://java.sun.com/j2se/1.4.1/download.html

As for learning a subject quickly, I think the CodeNotes (http://www.codenotes.com/do/books/book?bookID=5) books are excellent for this. The CodeNotes books are the antithesis of the Blah for Idiots books: they assume you are intelligent and can handle a fast-paced coverage of the subject without incessant repetition. They are usually only 200 pages. They are unlike most bloated Java books which try to take up lots of shelf space at the bookstore and appear to be comprehensive by adding lots of pages of filler.

I must say though, that I've read other CodeNotes books, but not the CodeNotes for Java book, so I don't know for sure if it is as good as the others. However, I imagine it is, because they seem to have consistently high standards and stick to their game plan for each subject.

Um, I hate to tell you this but I find it INCREDIBLY unlikely that you can learn enough Java in 2 days to contribute to a project. Working hard isn't going to save you.

I know it sounds harsh, but it's the truth. Personally, I wouldn't want to work for a boss who told me "You have 2 days to learn Technology X or else you're gone."

If you have a background in computer engineering, it shouldn't be difficult to learn enough Java (the language) to at least follow and understand Java code. While many books are useful, I always find that nothing really substitutes reading the language specification from cover to cover. Again, that assumes that you have a good knowledge and conceptual foundation of programming languages, etc. The Java Language Spec is available for free from the Sun Web site, and it is quite clearly written, with code examples, etc. By its very nature, the language spec is comprehensive, and reading it might actually give you an advantage over those who learned Java "second hand" (from books and tutorials).

By now you probably have a day only, but hope this suggestion helps.

BTW, Java is a relatively small language. Of course, there are many Java APIs, but you might be able to satisfy your boss' requirement with knowing something about the language only.
