instantiated when static methods in the class are executed. If you are using Singleton, the only instance that is generated will always be in memory and will not be purged by GC (because static attribute variables are not purged by GC) unless the entire JVM exits. I thought about it for a few days, and I wrote the code myself to do an experiment. Point three: (good! )because of the DAO initialization, will be compared to the system resources, if the static method to take, will continue to initi

Event Delegation Principle : event bubbling mechanism.Pros : 1. You can save a lot of memory footprint and reduce event registration. For example, UL agent all Li's Click event is very good.2. Can be implemented when new sub-objects, no longer need to be bound to the event, the dynamic Content section is particularly appropriatecons : The common application of event agents should be limited to the above requirements, and if you use event proxies for all events, event errors may occur. Events tha
