Answer Posted / anuja joshi
The major difference between Java and C++ is the behavior of object variables. In C++, object variables hold values, not object references. Note that the new operator is never used when constructing objects in C++. You simply supply the construction parameters after the variable name.
Point p(1, 2); /* construct p */
If you do not supply construction parameters, then the object is constructed with the default constructor.
Time now; /* construct now with Time::Time() */
This is very different from Java. In Java, this command would merely create an uninitialized reference. In C++, it constructs an actual object.
