With version 5, classes have been introduced to PowerShell. If you are coming from a developer background, you may already be familiar with classes. A class is a data structure for storing properties and methods. Classes in PowerShell, though, have some limitations and are very rarely used.

The first example is very straightforward:
#Class with constructor
