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.
Go to the UML tab.
In the UML tab, you can create a class.
Create a class for example Greeting.
Right Click, New >> Class
Give the name of the class: Greeting
Add a new data field called message.
Add a getter method getMessage()
Add a constructor for the class Messenger. This method is invoked when we create the object in the main flow chart.
Steps to create and invoke the Greeting class in the main tab:
- Design the main flow chart.
- Create a variable 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 method.
- Run and check the output of the flow chart.
That’s it. Hooray..! We have modeled a class and created an object to print “Hello World!” on to
the console window.
