Java类的类图的实现

Question

I wanted to know how i can design a uml class diagram or uml diagrams in General of These Java classes:

public class A{
 private A parent;
 private B[] b = new B[3];
 protected int i;
 private Vector<C> c; //container for objects of class C
 }

 public class B {

 }

 public class C {
 private A owner;
 public A getOwner() {return owner;}
 }

Maybe someone who has the Software can post an example how an class diagram in uml can look lie with These Java classes.

Answer 1

Something like this?

EDIT0: and a simple object diagram sample


Edit1:
explanation: in object diagram you should specify the value of each variable, here the i=1990 is an example, it could be any number.

A a=new new A();
a.setI(1990);

as you see, there are two instances of class A named a and a1 .

A a=new A();
A a1=new A();

The a1 reference has no value for variable c, so it's null .

class B doesn't have anything(attribute) here.
in class A , the b variable is a array of class B , so a variable has two B references( b0 , b1 ) and a null value.

B b0=new B();
B b1=new B();
a.setB(new B[]{b0,b1,null});
////
B b2=new B();
a1.setB(new B[]{null,null,b2});

and about the :C and :Vector<C> , why doesn't it have a name lie a1 or b0 ? because there is no need for pointer(reference) for the class, so it doesn't need a pointer, in other word an object from Vector<> and two objects from C are created and passed to the host class A .

a.setC(new Vector<C>());
a.getC().put(new C(a));
a.getC().put(new C(a));

and about the owner in C class, assume that the owner is set during the object creation by constructor, or has set by a indirect reference (using Ac ).

I hope I could give some hand dude. Software: UMLet
