Lab 1.6.3 Exploring BlueJ Tutorial

Estimated Time 30 minutes

Learning Objective In this lab activity, the student will explore BlueJ by working through the tutorial that is provided with the IDE.

Description/Scenario • The BlueJ Integrated Development Environment (IDE) is used to build Java programs. It is important to understand that the BlueJ program merely makes the process of editing, compiling, and running programs easier and faster than using the command line. BlueJ automates several of the tasks for the programmer. In order to compile a Java program, BlueJ still uses the javac program. An example of this was done when compiling the HelloStudent program from the command line. BlueJ also uses the same JVM (java) that has been used at the console window when it is told to run a program. • BlueJ has an online tutorial that is simple to follow and well written. However, some terms that are specific to Java may be encountered. Some of these terms have not been covered because the tutorial assumes the reader is an accomplished Java programmer. Do not worry about these terms for now. They will become familiar as the course proceeds.
