Beginning C# 2008 Objects: From Concept to Code

3.10. Summary

In this chapter, you've learned the following:

• An object is a software abstraction of a physical or conceptual real-world object.

• A class serves as a template for defining objects; specifically, a class defines the following:

  • What data the object will house, known as an object's fields

  • What behaviors an object will be able to perform, known as an object's operations (methods)

• An object can then be thought of as a filled-in template.

• Just as we can declare variables to be of simple predefined types such as int, double, and bool, we can also declare variables to be of user-defined types such as Student and Professor.

• When we create a new object (a process known as instantiation), we typically store a reference to that object in a reference ...
