3. What is generics?

4. What is generics?
ensure type-safety
the compiler will validate types while compiling, and throw an error if you try to
assign the wrong type to a variable.

6. Benefits
No Casting, and Boxing
Increased Performance
Ensured strongly-typed Model
Reduced run-time errors

7. Namespace for Generics

16. Iterators

17. Iterators
is a way of navigating through the values in a collection.
specify the way values are generated when the foreach statement
accesses the elements within a collection.

Return Infinite values
Reduce Complexity
Save Memory
