Creating and Using Objects

• Class provides the blueprint for all objects (objects are created from the class)

• There are three parts of creating an object: Declaration, Instantiation, and Initialization.

• You can also declare a reference variable on its own line to refer to an object.

Extending Objects

• Usually involved inheriting another object within classes and subclasses.

• syntax: "class childclass extends parentclass"

• syntax: "class parentclass extends in-built-object"

• You can also extend two objects at once/.
