Why we chose BlueJ Interactive Easy to use Ideal for introductory programmers Shows relational diagram much like UML Visual effect for abstract concepts Implemented in Java Runs on all platforms Debugging features Free !

BlueJ’s effect on OOP think in terms of objects – the fundamental units foundations From a class create objects OR to create objects we need a class From an object invoke a method OR to use a method there must be an object Objects exist independently and operations can be executed on them.

The BlueJ Environment At the functional level -- Objects At the operational level -- Methods For a beginner these abstract concepts are difficult to grab. Visual effect with object and class diagrams and the relations between classes has higher impact in learning and understanding. BlueJ provides an environment to create and manipulate objects interactively.

BlueJ as an OOP environment Step 1: Create objects. and visualize the outcome Step 2: Manipulate method and visualize the outcome Step 3: Modify existing method. and visualize the outcome Step 4: Add/Create methods. and visualize the outcome Step 5: Create classes. and visualize the outcome Step 6: Establish a relation. and visualize the outcome
