Good-day

Please assist with correct code as per below reviewer comment.

Corrections 2B made

There are a few suggestions that I would like to make for you to meet the task's requirements. I would suggest making use of a menu that gives the user the following options and any others you think may be useful, instead of just asking the user to start adding the architect's details. This can help to make it to improve the experience for the user while also meeting all of the tasks requirements. 1. Reads details about existing projects from a text file and uses this information to create a list of project objects. - You want to ensure the program still works even if the user does not select this option. 2. Allows a user to add new objects to this list. 3. Allows a user to select and update or finalize any project on the list. 4. Allows a user to see a list of projects that still need to be completed. 5. Allows a user to see a list of projects that are past the due date. 6. Writes the updated details about the projects to the text file when the program ends. *I would recommend making a different menu option for each of those requirements, and making use of methods to organize your program and improve its readability.

As part of the tasks requirements doc comments should be used to generate documentation with the Javadoc tool, below I share a helpful link on this.

Lastly, another part of the requirements is to make use of exception handling within your program, for example what happens if the user enters a string for telephone number instead of a number.

TASK Follow these steps: Design your program to meet the specifications given by the client. Extend the program that you have written in previous Capstone Projects so that this program also: o Reads details about existing projects from a text file and uses this information to create a list of project objects. o Allows a user to add new objects to this list. o Allows a user to select and update or finalise any project on the list. o Allows a user to see a list of projects that still need to be completed. o Allows a user to see a list of projects that are past the due date. o Writes the updated details about the projects to the text file when the program ends. Besides meeting the above criteria, you should also do the following: o Make sure that your program includes exception handling. Use try-catch blocks wherever appropriate. This should include ensuring that your program handles exceptions related to writing or reading to/from text files and exceptions related to acquiring user input. o Make sure that you have completely removed all errors from your code. Take extra care to ensure that logical and runtime errors have been detected and removed. o Make sure that your code has been adequately refactored. o Make sure that your code is adequately documented. Adhere to the style guide found here. o Use Javadoc to generate API documentation from documentation comments for your program. Submit your fully debugged and refactored code and the documentation for your project to a code reviewer. After receiving feedback from a code reviewer and improving your code based on this feedback, add your program to Github.
