constructor - get/set methods and constrcutors in class diagram -


recently assigned develop use case diagram , class diagram conference management system.first developed use case diagram , class diagram. in class diagram have following unclear parts:

  1. do need show , set methods private fields in every class. or can omit , set methods, since obvious.
  2. do need show constructors in class? if not necessary, reason not showing them? have seen lot of class diagrams without constructors reason beyond understanding.

any on above questions appreciated.

gets , sets methods not uml definition. way how manipulate attribute values in programming languages. pure uml know attribute , type, name , other properties.

typical usage of getters , setters in programing implement readonly or derived (calculated) attributes.

you not have define getters , setters in uml class diagram.

constructor:

you can define constructor operation in class of course. constructor operation has keyword "create" @ beginning of name. can assign behavior definition constructor method define how construct instance of class.

see common behavion in uml superstructure.
