oop - get() whats the diff? -

whats difference between these two?

pvector = new pvector(10,12); pvector b = a;

and

pvector = new pvector(10,12); pvector b = a.get();

i realise get() returns re-create of pvector, whats difference other one?

thanks

in first example, b , a reference same instance of pvector. therefore, if alter a.x or a.y, alter reflected in b well.

the sec copies pvector. changes 1 won't reflected in other they're separate instances of object.
