Answer Posted / uday
We use boxing and un-boxing when we assign a value to an
object and vice-versa.
Ex:
Int i=10;
Object o=i //this is boxing
int j=(int)o; //this is unboxing
When u say boxing, an object box is allocated and then the
value is copied to that box.
When u unbox, the value is copied out of the object box and
copied into storage location.
