I didnt make my statement clear enufin this case, a shallow clone will make an extra copy of Vector object. ( only container object is copied) however, a deep clone will create memory for Vector object and all String objects inside this Vector. ( container and contained objects are all duplicated)

[java] how to cast after clone()? Vector a= new Vector(); Vector b= a.clone(); //1. Vector b=(Vector) a.clone();//2. Vector b=(Vector) a. clone(); //3 i have tried all the three ways of casting, but all of them will produce either an error or a warning. Can anyone suggest how to do casting in this case? thanks a lot in advance!
