Hi guys, Do you see any problem implementing the two methods Data.lock() and Data.unlock() outside Data class, for example in a lockManager not subclassed from Data. The instruction says: Part of your assignment will be to enhance the Data class. You may do this by modification or subclassing, but you should document the approach and reason for your choice. Thanks for your help. Charles.
