A Beginners guide to learn BlueJ Key Features

• Book contains 210 programming problems and solutions.
• Book is devoted to those entire learners who face problem in learning BlueJ.
• Each program is explained in simple way.
• Book covers the program from basic level to master level.

Description
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. What Will You Learn
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. Who This Book Is For
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. Table of Contents

SK Wasim Ali learned BlueJ programming while he was student of class VI of CISCE Board school in 2002. He completed his post-graduation on Computer Science from the University of Burdwan, India in 2015. He had guided and trained many student of Computer Science while pursuing his education. He worked in several industries for sometime, but due to his passion for learning nature and training students, he left industry. He has good knowledge about different programming languages, data security and web.

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.

PicPic: 10 - Click on New Class, to create a class file.

PicPic: 11 - Give Class Name in text box and Click on ok.

PicPic: 12 - Double click on created classes to open the class file.

PicPic: 13 - Class file will look like this. Now delete everything auto-generated in page and write a code by self.

Pic: 14

PicPic: 14 - I have written a "Hello World" program as an example to start with.

public class hello

{

public void display()
{

System.out.println("Hello World");
}}

After writing the code, click on compile button and check for any syntax error. If no...
