Modules Creation « Language Basics « Ruby

1.Modules and Namespaces
2.Modules provide a structure to collect Ruby classes, methods, and constants into a single, separately named and defined unit.
3.Creating Modules classes inside modules.
5.access methods inside classes inside modules with Ruby scope resolution operator (::)
6.Involve demonstrating two classes with the same name, but in different modules to create a module and then include it in a class.
8.require the file containing the module, and then it would work (again, require is expecting a name in the load path).
9.prefixed with the module name you can call the method from anywhere, as is the case with the Math module.

10.Initializing Instance Variables Defined by a Module
11.Abstract method in a module
12.Use remove_const to delete a constant definition
13.Avoiding Naming Collisions with Namespaces
14.Print all modules (excluding classes)
15.Print all classes (excluding exceptions)
16.Print all exceptions
