The Java programming language has been one of the most powerful tools available to computer programmers since its inception in 1995. It has also consistently changed since then, making it a vast and powerful resource for object-oriented programming today. This lucid textbook introduces the student not only to the nuances of object-oriented programming, but also to the many syntaxes and semantics of the modern Java language. Each concept of programming is explained, and then illustrated with small but effective ready-to-run programs. Important points to be noted have been emphasized and hints have been given at the end of each discussion so that programmers are careful to avoid common pitfalls. Finally, a number of practice problems taken from real world scenarios encourage the student to think in terms of problem solving, consolidating the knowledge gained.
