A programmer wants to modify the Converter class so that the buildString method stores the value it returns so that the value is available to other methods in the Converter class. The programmer would like to implement this change without making any changes to the signature of the buildString method or overloading buildString.

You need to write a description of how you would change the Converter class in order to support this modification. Do not write the program code for this change.

Make sure to include the following in your response.

• Identify any new or modified variables or methods.
• Describe, for each new or revised variable or method, how it would change or be implemented, including visibility and type.
