An inner class is said to be a member of the outer class. Does that mean that whenever an object of the outer class is created, an instance of inner class is also created implicitly?

No. An instance of the inner class is created only when you instantiate it.
Note that the constructor of the inner class requires an instance of the outer class (although this is masked by the compiler). This is true for non-static nested classes. Static nested classes can be instantiated without a parent instance (since they are static)
