C++

Following are some of the differences between C and C+. When compared to C+, C is a subset of C+. All valid C programs are valid C+ programs. C is a structural or procedural programming language, while C+ is an object oriented programming language. In C, Functions are the fundamental building blocks, while in C+, Objects are the fundamental building blocks. C doesn't have variable references, while C+ has variable references. C uses malloc and free for memory allocation while C+ uses new and delete for memory allocation. C does not provide direct support for error handling, while C+ supports exception handling that helps in error detection and smooth handling. C does not support function and operator overloading, while C+ supports both function and operator overloading. C doesn't support Generic programming, while templates in C+ allow to write generic programs. C doesn't support namespaces while C+ supports them.

Head First Java: Head First Java was the first Java related book that I read, almost 9 years ago. This is a great book and you should read it. The best part of Head First Java is the simplicity of the book and how easily it relates Java programming concepts to real life.
Java: A Beginners Guide (Sixth Edition): As the name suggests, it's a good book for someone with basic knowledge of programming wanting to learn Java programming language. It's written by Herbert Schildt and covers all the basic concepts of Core Java.
Java: The Complete Reference (Ninth Edition): This book contains everything you need to become master of Java programming language. You can keep this book as a reference. Although I think it's not a good book for complete beginners, because its more than 1200 pages long. But if you want to learn beyond the basics, then this is the book I would recommend.
