Objects First with Java: A Practical Introduction Using BlueJ/* 0-13-044929-6, 4492J-5, Barnes, Kolling, OBJECTS FIRST WITH JAVA */" BlueJ is a Java development environment that runs on top of the Sun Microsystems Java Development Kit making use of the standard compiler and virtual machine. It allows readers to create objects of any class and interact with their methods. For the first time, the traditionally difficult concepts of objects and classes are brought alive in an easily manipulable visual form. This truly " objects first" approach within the customized BlueJ environment will revolutionize the way programming is learned. The book includes a copy of BlueJ." Takes a project driven approach to problem solving--the book is structured along the lines of fundamental development tasks--providing readers with clear coverage of the principles of object-oriented programming." Programmers and non-programmers who want to learn Java with a state of the art approach and user-friendly programming environment. |
