Wheares in Java instead of Inheritance, we can use Interface

Answer / sravanthi
c++ is not a pure object oriented programming language where
as java is a pure object oriented language.i.e.,some opp
concepts like multiple inheritance,encapsulation etc is not
supported by java.in place of multiple inheritance interface
is introduced.and java does not support pointers as they
create some problems like crashing,terminating etc.java is
plat form independent where as c++ is plat form dependent
i.e.,in java we can write pgm once can run it anywhere.java
supports internet where c++ does not.c++ is a compiler,whereas
java is a both an interpreter & compiler.

Question In a class, there is a reference or pointer of an object of another class embedded, and the memory is either allocated or assigned to the new object created for this class. In the constructor, parameters are passed to initialize the data members and the embedded object reference to get inialized. What measures or design change should be advised for proper destruction and avioding memory leaks, getting pointers dangling for the embedded object memory allocation? Please suggest.

What measures or design change should be advised for proper destruction and avioding memory leaks, getting pointers dangling for the embedded object memory allocation? Please suggest. Answer # 1 use copy constructors 0 Shanthila There is something to be taken care in destructor, in copy constructor, suppose the memory is assigned to the embedded member object pointer with the parameter passed value, but if some other objects of different class also are pointing to this memory, then if some one deletes the object then this class member pointer object will become dangling, or if the object is not deleted properly then there will be memory leak. Please suggest the design change required to handle or avoid this situation
