Video Description
Methods let you write code once and use it everywhere! This is how we build complex programs from simple, testable pieces.
What you'll learn:
- Creating and calling methods
- Method anatomy (access, return type, name, parameters)
- Parameters for input
- Return values for output
- Method overloading
- Optional parameters with default values
- Named arguments for clarity
- Pass by value vs reference (again!)
- Method scope and local variables
- Expression body methods
- Best practices for method design
Key principles:
- Single responsibility - one method, one job
- Keep methods small (under 20-30 lines)
- Meaningful verb names (CalculateTax, not Process)
- Consistent parameter ordering
