Java has been one of the most popular programming languages for many years. Java is Object Oriented. However, it is not considered as a pure object-oriented as it provides support for primitive data types (like int, char, etc). In this article, the difference between BlueJ, a Java IDE and JDK is discussed.
BlueJ: BlueJ is a free Java environment started in 1999 by Michael Kolling and John Rosenberg at Monash University, Australia as a successor to the Blue J. It is a windows based platform for Java Development Kit (JDK). It is required to install JDK version 1.3 or more before installing BlueJ. It can be freely downloaded from its official website. It was developed to support the learning and teaching of OOPs(object-oriented programming). The objects can be interactively created and tested. BlueJ has a simpler interface than most of the professional IDEs. It offers many tools that are specific to its educational goals. There are also standard development tools available, such as an editor, compiler and runtime environment.
JDK: JDK stands for Java Development Kit. It is an implementation for java platforms released by Oracle Corporation for Java developers on Solaris, Linux, macOS or Windows. JDK is a development environment which is used for developing Java applications. It is necessary to compile the code and convert java code to byte codes. It also includes compilers and debuggers. The JDK allows the developers to create programs in Java that can be executed and run by the JVM and JRE.
The following table explains the difference between BlueJ and JDK:
BlueJ JDK 1.3 It is an Integrated Development Kit where we can run java. JDK is a package which is required to run java programs. BlueJ is a platform that helps with the interaction between a coder and the system. This can be considered as a resource to build various apps in java. It is a Windows based platform. It is a DOS based platform. It is comparitively easier than JDK as it offers compilation and debugging at the same time. It does not offer compilation and debugging at the same time. It supports the syntax of JDK 1.3 It does not support the syntax of BlueJ. It has a default package class. It does not have a default package class. Because of the presence of default package class, it makes more easy to use and stated as user friendly. As default package class is not available, it makes it harder to use and is not user friendly.
