Classes

Class Name

Attributes

Operations

A class is a template for actual, in-memory, instances

4

Attributes - Signature[visibility] name [[multiplicity]] [: type] [=initial value] [{property}]

+ isLightOn : boolean = false

- numOfPeople : int

mySport

+ passengers : Customer[0..10]

- id : long {readOnly}

5

Operations - Signature[visibility] name [(parameter-list)] [: return-type] [{property}]

+ isLightOn() : boolean

+ addColor(newColor : Color)

+ addColor(newColor : Color) : void

# convertToPoint(x : int, y : int) : Point

- changeItem([in] key : string, [out] newItem : Item) : int
