Cloning multidimension arrays

Cloning multidimension arrays results in shallow cloning. Have understood that from below exampls.
Can someone explain using diagram - (like Corey explained the GC concepts on this site...) as to how the shallow copying is working



Produces the following output:
false I2:79
I3:3
false I22:79
I33:79


Thanks a lot !

I don't understand your example. You clone() I2, then test for equality of reference between I2 and I3, which is going to be false. Then you change the value of I2[0] and print it. Then you print out I3[0].

What are you trying to demonstrate?
