Hello World Object Oriented Flowchart

Introduction

In this post, we will learn RAPTOR Object-oriented flowchart by creating a class and invoking it in the main flow chart. We will create a simple plain class called Greeting. It stores a string message and returns when invoked by a getter method.

Object Oriented Flowchart

Launch RAPTOR flowchart tool.

Enable or switch to Object-oriented mode.

Mode >> Object-oriented menu option.

Save the flowchart on the machine.

File >> Save As menu option.

Steps to create and invoke the Greeting class in the main tab:

  • Design the main flow chart.
  • Create a new variable str that stores the message.
  • Create an object for the Greeting class.
  • Pass the variable to the constructor of the class.
  • Output the information from the object getter/accessor method.
