    About this ebook

    This book will help students to get standard BlueJ problem and solution. They will not have to worry while learning BlueJ practically. Moreover, this book will help teachers to get different problems and try to do those in different ways. This will help both beginners and expert to get idea and support while learning BlueJ.

    Some of the coding problems in the book have been taken from the real life projects, which will be highly beneficial for the students.

    Blue Java is the basic programming language would be better to learn before learning vast Java. This enables the learner to think logically, this enables learner to see Java Virtual Machine (JVM) working process. So, many critical features of Java can be tested at an early stage using Blue Java.
    These programs won’t make you topper anywhere; but practicing this programming problems will make you expert to solve any logical operation of any BlueJ program.

      BlueJ Programming - SK Wasim Ali

      Preface

      Welcome to BlueJ Programming Problems & Solution. I am glad you've decided to learn about BlueJ.

      If you've picked up a copy of this book, you will sure get solution of every possible program's can be done by using BlueJ. Basically, Bluej is a school level programming languages which can be learned to gain in-depth knowledge about programming concept, logic and process.

      Learning something new is always difficult at first. But your daily practice could bring success to your hard work. I am writing this book to bring small guidance for student who fears BlueJ programming.

      In market, there is not yet especially any book for sample programming problems with solutions for BlueJ. I believe this book will help many students to learn BlueJ.

      Who should read this book

      This book is aimed for students who want to learn BlueJ programming practically, for students of school. This book will help to see the basic programming problems, learn lots of logic based skill same for every programming language, just may need to edit little for different languages.

      What's in this book

      This book had different programming problems from beginner to master. This book contains many examples question, which is asked at different process of examinations. This book will help you to find the solution of any associated program. I have seen, many students face problem as BlueJ is not well famous programming language, as it cannot be used to bring real world output. So, authors don't like to waste time computing something for students. I too faced this problem many time. So, I made a decision to write this book for all students and help them providing simple guidance.

      CHAPTER 1

      INTRODUCTION TO BLUEJ

      The development of BlueJ was started in 2000 by Michael Kolling and John Rosenberg at Monash University, as a successor to the Blue system. BlueJ is an IDE (Integrated Development Environment). Blue was an integrated system with its own programming language and environment. BlueJ implements the Blue environment design for the Java programming language.

      Presently, BlueJ is maintained by a team at the University of Kent, England.

      What is BlueJ

      BlueJ is an integrated development environment (IDE) for the Java programming language, developed mainly for educational purposes. It is a small part of vast Java. BlueJ runs with the help of java development kit.

      It is basically developed to support the learning and teaching of Object Oriented Programming Language. The main screen graphically shows the class structure of an application under development (in a UML-like diagram), and objects can be interactively created and tested. This interaction facility, combined with a clean, simple user interface, allows easy experimentation with objects under development. Object-oriented concepts (classes, objects, communication through method calls) are represented visually and in its interaction design in the interface.

      How to install BlueJ

      To install BlueJ, you need to download BlueJ first and Java IDK. Follow the steps. You can get the bundle from official website directly https://www.bluej.org/ . You can download the version you need for your specific system: https://www.bluej.org/versions.html .

      There can be two states, either you had already installed JDK in system, so you just need to install BlueJ; so download the file less then 20mb size which is not bundle.

      Else, if your system doesn't have JDK (Java Development Kit) installed, then download the Bundle package of BlueJ.

      After downloading let's do installing. Follow the steps as per image.
