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

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,

Code has been uploaded github+gitee, at the end of the article has an address The book connected to the above: in the first few articles, we took three days to simply understand the next interface document Swagger Framework, has completely liberated our previous Word document, and can be debugged online, and when the project started, we can define some empty interface, or can return false data, This really reached the front and back end does not wait

However, after all, the process overhead is relatively large, and the design process data synchronization, interprocess communication and other operations relative to the thread is very complex, but also a pain in development, we often for performance and discard the use of Python to use the C multithreaded solution, but does reduce the co

When do you use this? When stored, the up

classes, in which style_fields = {' Field ': ' Ueditor '} and then adding the Modeladmin class to the corresponding registration object, you can use the Rich Text editor when you edit the field in xadmin background. To get back to the point, Djangoueditor also needs to define the required field in model as Ueditorfield, which inherits from TextField, which has the upload path configuration for pictures and attachments, but does not give the upload path configuration of the video directly, Then

hierarchy . Collection represents a set of objects, also known as Collection elements . Some collection allow duplicate elements, while others do not. Some of the collection are orderly, while others are unordered. The JDK does not provide any direct implementation of this interface: it provides more specific sub-interfaces (such as Set and List) implementations. This interface is often used to pass collection and operate these collection where it is required to be the most universal.Collection

using object, just write an object, then anything can be solved, now do the qualification, only a part of the type can come in, if not this type or its subclass, then the direct compilation fails. Before it was compiled nothing, run out of trouble.Many of the updates in Java now are run-time errors that go to compile time, which is more secure.The generic type of the qualified knowledge point is specifically written as follows, after qualification, you can directly take the inheritance method.

One.What is a generic interface? The previous example created so many classes that it was cumbersome.The first thing to understand is that the interface is an abstract class, and after the declaration, the following class is implemented. The methods in the interface are the classes that are implemented. This combines the interfaces with generics. In the preceding chapters, you combine generics with classes, methods.A generic definition on a class is a generic class that is defined on an interfac

,When importing a list package, the list has the name in different packages in Java, and the java.awt package or Java.util package has a list. If the window comes out and returns directly, the java.awt package is imported. In the continuation, the method of invocation is not seen.which element is deleted and which element is returned. Remove can change the length. In order to know more clearly, the light knows to delete a certain corner mark, but also to return let us know what the deleted eleme
