    Raptor Flowchart

    Hello World Object Oriented Flowchart

    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.

    Launch RAPTOR flowchart tool.

    Enable or switch to Object-oriented mode.

    Mode >> Object-oriented 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.
    • Run and check the output of the flow chart.
