Lumen is being used to inherit the core and advantages of laravel.It is quite easy to write, that is, the performance i
One.I'm done with the map collection, by the way, little things.A common subclass of the map collection:Hashtable research is data structure, hash in 1.0 out, there is no table. At that time, single-column collections were only vectors, and double-row collections were hashtable. The internal structure is a hash table. is synchronous. HashMap and Hashtable are different, the efficiency is no longer said. is a HashMap API note that is not synchronized.H
the E-containerThe object (it) must be dependent on the container for the element to be fetched, because the data structure of each container is different, so the iterator object must be implemented inside the container, and for the container holder, the implementation is unimportant, as long as the object of the iterator to the implementation is obtained through the containerThe iterator method.The iterator interface is the common interface for all collection containers to be removed from the

HashTable: the internal structure is a hash table for synchronization. This implementation provides all optional ing operations and does not allow the use of null values and null keys.

, directly printing is a large string, to take out the inside of something difficult to fetch. You can now remove any element by means of an iterator.The use of iterators, first to judge there is no, then a fetch. (now it's all part of the story)What is the other method of extraction?Iterator it is a reference that can be used by it at the end of the while. It.next (); it can not be taken, although it is not available, but it is still in use, in other words, it is in memory.As the iterator ends,

The following display is not possible, once the generic type is used, the variable type is indeterminate, how can you use a specific object method, in case the person type is passed, how can be written str.length ().
