Digital Solutions DESCRIPTION This book will help the students to learn programming in an effective and interactive manner. This book contains an ample amount of interactive programs for the students to practice and learns programming. This book will help the students to learn the fundamental concepts of Object-Oriented Programming in Java. The programs are designed to develop the learner’s analytical thinking so that they are able to understand and develop programs on their own. To help the student understand the concept of programming, the codes are written clearly and neatly with line numbers and proper indents. These programs have been executed in the BlueJ Development Environment. All the codes are accompanied by their outputs. These codes are presented as they appear on the BlueJ platform. All the keywords appearing in the code are coloured as they appear in the platform respectively. This book also contains sample question papers to provide the learners with a grasp of what the question paper looks like. The book also contains previous year’s questions from the past decade to cover as many questions and their variations.
