It doesn't support *C style* pointers. Its idea of a *variable* is
(in C) a pointer to an object:
If you define a variable like this:
MyClass myClassVariable;
"myClassVariable" is *not* an object, it is a (null-initialized)
reference to an object, so if you do the following
MyClass m0 = new MyClass();
MyClass m1;
m1 = m0;
The variables m1 and m2 both "point" (in a C sense) to the same object.
(Someone check all this stuff! I have only been using Java about a
month and lightly at at that, so I could be completely off the beam.)
