what does the above code do??
does it make one reference variable a and assign it a new Animal object during each iteration. and in the end we have 20 Animal objects added to aList and a refers to the last one and other 19 left without any reference??

Yes, 20 Animal objects are created, and after the loop is done, they are all eligible for garbage collection since they are not referenced.
