Static Structural Diagrams 2 แสดงแผนภาพของคลาสทเชอมตอกนดวย ประเภทของ Static Structural Diagrams � class diagram : classifier view � object instance diagram : instance view static relationships

Classes in UML 4 เขยนได 2 รปแบบ Class name Person Attributes attribute name : type Operations operation name(parameter : type) : result type Person - Tax. IDNo : String - Name : String + Income : double + Tax. Paid : Boolean + calc. Tax() + calc. Tax. Bal()

UML Syntax for Attributes 5 visibility name : type + id : String � visibility: public (+), protected (#), private (-) การตความไมขนกบ � name : เปน string � type : ประเภทของขอมล programming language dependent ไมขนกบภาษา

UML syntax for operations 6 visibility name (parameter list) : return-type-expression + assign. Agent (a : Agent) : Boolean � visibility: public (+), protected (#), private (-) การตความไมขนกบ � name : string programming language � parameter list : arguments � return-type-expression : ประเภทของคาท return ไมขนกบภาษา

Objects in UML 9 เขยนได 2 รปแบบ Object name Tim: Person Attributes attribute name : type = value Same Operations for all instances of a class Tim : Person Tax. IDNo=“ 23003” Name=“Tim. Lim” Income=“ 30000. 00” Tax. Paid = FALSE calc. Tax() calc. Tax. Bal()
