Hi,

The following book is also recommended for getting one of the first java certificates (SCJP):

http://www.amazon.com/SCJP-Certified-Programmer-Java-310-065/dp/0071591060/ref=sr_1_1?ie=UTF8&qid=1316600840&sr=8-1

I used Objects First With Java: A Practical Introduction Using BlueJ (4th Edition) by David J. Barnes and Michael Kolling.  Priced like a college textbook because it is.

However, you can download BlueJ for free.    http://www.bluej.org/   This omits the instruction but does provide you with an IDE (of sorts) and program source code, both good and bad examples.

I'm guessing you don't have tuition reimbursement available.  If you do, you could take a course (except many colleges already started).  Sometimes it's useful to have someone review your code.  (Of course, you could post code here and get help.)

One advice on learning any language...

Learning just the syntax is not sufficient, what's more important than the syntax is to understand the culture of the language. Learning the syntax along with the culture would help to write useful code, else we would end up in writing junk code.

for java, we need to understand the object oriented programming principles, etc...

Following up on arundhaj.  I agree.  I think that leads to a question for the author -- what do you already know about OOP principles?  I don't know VB.NET so I don't know what you know about the OOP principles.  Do you know these terms?

Encapsulation
Polymorphism
Inheritance

This is only a partial list.

I would still get a Java book that also teaches OOP concepts.  There's a vocabulary to learn if you want to communicate with others using Java.

Functions in C++ would be called methods in Java.   A method such as getFirstName() would be called an accessor in Java but a getter in C++.  (Although some using C++ still say accessor.  I'm one of the some.)

I have a learning suggestion once you know Java.  You might want to study Data Structures and Algorithms.  You can find out how ArrayList, Hashing, etc work (if you don't already know how they work).  You can learn to avoid the infamous bubble sort...
