What is copy constructor in Java with example?

Is copy constructor added by default?

The compiler also creates a copy constructor if we don't write our own copy constructor. Unlike the default constructor, the body of the copy constructor created by the compiler is not empty, it copies all data members of the passed object to the object which is being created.
