For introductory courses in Java/Introduction to Programming and Object-Oriented Programming. With its emphasis on visualization and interaction techniques, teaching students objects from day one is now possible with "Objects First with Java, 4/E." It uses BlueJ to get students started on object-oriented programming from day one - unlike most texts, which delay coverage - so that students don't have to switch thought processes midstream. Barnes and Kolling strategically do not cover traditional topics like control structures, preserving their goal of teaching object-oriented principles. The authors incorporate a spiral approach throughout the text. This introduces a topic in a simple context early on, then revisits it later to increase student comprehension. This enables the understanding of many topics while broadening knowledge. Loaded with projects, the book is organized around software development tasks versus the language features to promote good problem solving skills. The number of interesting examples provides student with lots of applications
