BlueJ is an IDE designed for beginners. It has a built-in editor, debugger, and viewer. An editor
                  provides us an area to write programs, and a debugger helps us by identifying errors in the
                  programs. On the other hand, the viewer shows the output of the program.

                  BlueJ is a freely downloadable application. We can download it from https://www.bluej.org/.
                  After downloading the application, we need to install it on our computer.
