In this chapter, we learn about TreeSet.We first have a general understanding of TreeSet, and then learn its source, and finally through the example to learn to use TreeSet. The 1th part TreeSet introduction TreeSet Introduction TreeSet is an

Communication between the client and the service, although it can be implemented through IBinder, requires a shared business implementation, if the haunted of interprocess communication needs to be performed using Aidl (the Android Interface

Reentrantlock Introduction Reentrantlock is a reentrant mutex, also known as an "exclusive lock." As the name suggests, Reentrantlock locks can only be held by a single thread lock at one point in time, and reentrant means that reentrantlock locks

The so-called iterator mode, that is, iterator for different containers to provide a unified access mode. This paper takes the container in Java as an example to simulate the principle of iterator. Need friends can refer to the next 1. First define

A Problems with fonts in the C language There are two ways of displaying in C language, that is, text mode and graphic mode. As I know, fonts can only be controlled in graphic mode. Let's take a look at some of the fonts defined in C Name index

Data | structure | Array I have not seen the data structures in other languages, but I think Java implementations are ingenious--with classes and objects. An array of tables, the idea is very simple is to define a class to store a set of data, I

Bundle.putparcelable can implement passing objects, but the object's class must implement the Parcelable interface before it can be used. Here is a simple example of passing an object between the activity. Parcel realizes the serialization of

Web page | Download one. Objective: Microsoft's. NET Framework provides the following two namespaces for our network programming: System.Net and System.Net.Sockets. By using the classes and methods reasonably, we can easily write a variety of Web

Therefore, I think that this signal class if it can return the number, but also know which objects are waiting, which resources can be used, is very perfect, only to get these general figures, the precise control is not very significant. No better

Hibernate optimization method One: Batch modification and deletion In Hibernate 2, if you need to modify and delete any data, you need to perform a query operation, after the data to be modified or deleted, then the corresponding operation of the

LOB (Large Object) in Oracle Oracle can store very large data (possibly 4GB) so that it can be written to the database by serializing a file or any other object into a byte output stream (OutputStream) and then using the byte input stream (

The use of arrays to achieve custom ArrayList, in addition to basic additions and deletions and other methods, but also added to the API used in some of the methods to facilitate better understanding of the implementation of ArrayList, the

1. Why use bidirectional stacks? Through the previous blog-a special linear table (stack), it is not difficult to know the stack's sequential storage (array implementation) performance is relatively good, because it does not exist when inserting

The HashSet implements the set interface and is supported by a hash table. It does not guarantee the iteration order of the set, especially it does not guarantee that the order is immutable. public class Hashset extends abstractset implements
