not able to modify portfoliomanagerfactory to accomodate stockquoteservice. i easily implemented factory pattern in stockquoteservicefactory, invested a lot of time in portfoliomanagerfactory but am confused about instantiation of classes.
You just have to do the following steps.
- Create a new Instance of stockquoteservicefactory.
- Use the above instance to call getService() and store the result in stockquoteservice object.
- After that create PortfolioManagerImpl object and pass the stockquoteservice object as a parameter in it.
- Return PortfolioManagerImpl object.
