If I use the flyweight pattern so that I only store unique Time instances, I can reduce the maximum number of typical time objects to 96 (24 hours times four possible times per hour). The appointment application will still support odd times, but predictable use suggests that flyweight will dramatically minimize object creation and memory usage.

When we use flyweight we share common data between objects,Which data in these objects iin this example are similar that he share?

May you give me a simple example by code about flyweight?
Thanks in advance!

I agree. Here's the link:
