Determines the level of access other files have to the class data or methods

Stores an objects data

A blueprint what an object stores and how it behaves

The attribute is created once and it shared between all instance of the class. Class attributes can be accessed through the class name like Math.PI

Can only access class attributes, class methods can be access to the class name like math.Pow()

Special methods used for constructing objects

A constructor 0 parameters. When a class has 0 constructors a hidden default constructor is created that will set all objects to null, booleans to false and all other primitives to 0

The combining of data into a class

A method used to check equality of two objects

Used to make a variable constant

A method that allows public access to a private attribute

When classes store their data privately prevent unwanted modifications

Every instance of an object gets its own copy of the variable

Can access both instance and class variables. Can only be accessed via through an instance of class

Sets methods or attribute properties

A keyword used to denote that a variable is not referencing any object

A group of related classes

Data cannot be accessed outside the file

A method that allows private attributions to be changed publicly

A keyword used to access the current instance of the class

A method used to return a text version of an object

Other methods, default constructor, data can be modified by classes that share the same package or any subclass, setters, getters, constructors

Data cannot be acccessed outside the file, information hiding uses this type of data, attributes

Keyword sets an attribute or method to be a class attribute or class method
