Should it be like this???

Question

Hi,
When the double[], "loads", is changed in the second line, also the corresponding value in the ArrayList, "loads__", changes! Should it work like this? Seems very strange to me.
loads__.add(loads);
loads[1] = 345635;Regards,

PingenYes, the ArrayList.add method does not create a copy of the array passed to it, but merely stores a reference to it. So you have two references (the one in the ArrayList, and your "loads" variable) referencing a single object. Any change to that object will of course be seen by both references.
