This course is the third course in a series that aims to prepare you for a role working as a programmer. In this course, you will be introduced to the four main concepts in programming: Advanced String Operations and Dates, Modeling Classes, Development of Classes and Collections. Labs will allow the students to apply the material in the lectures in simple computer programs designed to re-enforce the material in the lesson. Learners will need to have a local machine with any one of the following operating systems; Windows 7 SP1 or higher, macOS 10.1.13 or higher, or almost any version of Linux from the last several years. The learner will either need to download the free community edition of Visual Studio or the open source .NET Core installation.

There are 4 modules in this course
In this module, we look at how we can persist data to files so that it will exist beyond a single execution of a program. We will look at how we can write data to files in both text and binary formats. We follow-up with ways to read that data back into the state of an executing program.

In this module, we look at how to implement the is-a relationships we modeled earlier in our UML diagrams through the use of Inheritance. Inheritance provides additional ways to abstract code in taxonomies where base classes share code with specialized versions of the classes. We will add a discussion about exceptions work in Visual Basic now that we can discuss inheritance.

In this module, we extend our implementation of the is-a relationships so that our code can work with specializations of a class without knowing the specifics of the specialization. This level of abstraction is known as polymorphism. Polymorphism provides additional ways to abstract code to work on objects in a taxonomy.

In this module, we continue our deep dive into the implementation of the is-a relationships. In our early work, we developed taxonomies for the purposes of abstraction. Now we want to think about the situation where a class could be in several taxonomies. This level of abstraction is known as an interface in modern programming. Interfaces provide signatures but not implementation so that we can use Polymorphism on objects that fall in multiple taxonomies.

Frequently asked questions
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
If you subscribed, you get a 7-day free trial during which you can cancel at no penalty. After that, we don’t give refunds, but you can cancel your subscription at any time. See our full refund policy.
