Another term for class attributes is fields. Accessing AttributesYou can access attributes by creating an object of the class, and by using the dot syntax ( The following example will create an object of the ExampleCreate an object called "

Try it Yourself » The The Multiple ObjectsIf you create multiple objects of one class, you can change the attribute values in one object, without affecting the attribute values in the other: ExampleChange the value of
Try it Yourself » Multiple AttributesYou can specify as many attributes as you want: Example
Try it Yourself » The next chapter will teach you how to create class methods and how to access them with objects. Main Content Specifying Class AttributesAll classes support the attributes listed in the following table. Attributes enable you to modify the behavior of class. Attribute values apply
to the class defined within the classdef (Attribute1 = value1, Attribute2 = value2,...) ClassName ... end Class Attributes
Specifying AttributesAttributes are specified for class members in the Superclass Attribute Values Are Not InheritedClass attributes settings are not inherited, so superclass attribute values do not affect subclasses. Attribute SyntaxSpecify class attribute values in parentheses, separating each attribute name/attribute value pair with a comma. The attribute list always follows the classdef (attribute-name = expression, ...) ClassName properties (attribute-name = expression, ...) ... end methods (attribute-name = expression, ...) ... end events (attribute-name = expression, ...) ... end end Class-Specific AttributesSome MATLAB classes define additional attributes that you can use only with the class hierarchies that define these attributes. See the specific documentation for the classes you are using for information on any additional attributes supported by those classes. Related Topics
Can you have an array in a class?Arrays as Class Member Data
If an array is used as member data of a class, the member functions can add in error-checking and boundary protection. Note that the array is allocated to size 10, but the list can have up to 10 items in it -- the "list" is not always "full"!
What is class variable array?A class is a heterogeneous data type: it defines any number of instance variables, each declared with its own individual name to store a different type of value. An array is a homogeneous data type: it defines one name storing an arbitrary number of indexed values, all declared to store the same type of value.
What are the types of arrays in Java?In Java, there are two types of arrays: Single-Dimensional Array. Multi-Dimensional Array.
