Hi,\nIn my scenerio, building up a class is a difficult task and cost a lot\nof time. I want to store a copy of the object, which has no specific\ndetail value. When request the object, I can clone a copy of that and\nuse the copy would not affect the original one, so I can change\nwhatever value of the cloned one and get another pure clones from the\noriginal. But I don't know how to use the clone() method suitablely,\nanyone helps? Thx!
