Learn the basic class-and-object model so Java programs can represent real things instead of only printing values.

Give your classes state with fields and behavior with methods so they can model something useful.

Use constructors to create objects with sensible starting values instead of manually filling every field after creation.

Use `this` to refer to the current object and make constructor or method code easier to read.

Protect object state by hiding fields and exposing controlled access through methods.
