Java Interlude 6: Mutable and Immutable Objects

These flashcards cover key concepts related to mutable and immutable objects in Java as well as related methods and class structures.

Mutable Objects

Objects that can be modified after they are created, typically through public mutator methods.

Immutable Objects

Objects that cannot be modified after they are created; any changes result in a new object.

Accessor Methods

Public methods that retrieve or access private data fields in a class.

Mutator Methods

Reference Variable

toString() Method

A method that returns a string representation of an object.
