SE450: Basics: Aggregation (Reference) [38/63]

file:Person.java [source] [doc-public] [doc-private]

01 02 03 04 05 06 07 package basics.aggregation; final class Person { //stdlib.Trace.graphvizShowSteps (true); stdlib.Trace.run (); final private String name; public Person(String name) { this.name = name; } public String toString() { return "Person(" + name + ")"; }; }

Reference to objects of another class:

   +--------+   name  +--------+
   | Person |<>------>| String |
   +--------+         +--------+

In UML, this is called aggregation.

Note that the aggregation refers to the instances of the class, not the class itself.

Class diagrams are static (describe the program text).
