This study guide covers mutator (setter) methods in Java. It explains their purpose (changing instance variable values), structure (typically void with parameters), and contrasts them with accessor methods. The guide demonstrates creating mutator methods within the Student class example, while highlighting the concept of immutable classes (like the Assignment class) which lack mutators. Finally, it shows how to use mutator methods to modify object states.
