Methods: Turning an English Task into Code

Where you are: Week 0 review > Methods

This part of the review is three short lessons. Work them in order:

1. The method header and how a method works: the fixed header slots, typed versus void, and returning a value.
2. Turning an English task into a method: reading the return type, name, and parameters out of the sentence before writing the body.
3. Pass-by-value: the copy rule: why a method gets a copy of a primitive, and what that means for the caller.

Finish all three before moving on to arrays, search, and sort.
