Java Reflection detailed This article is still using a small example to illustrate, because I always feel that the case driven is the best, or only to see the theory, read also do not understand, but suggest that after reading the article, in retrospect to look at the theory, will have a better understanding. Start the text below. Case 1 Gets the complete package name and class name from an object

first, before introducing polymorphism, introduce an important knowledge point--java type of reference variable There are two types of reference variables in Java: 1. Compile-time type , which is determined by the type used when declaring the variable; 2, the Run-time type , by the actual assigned to the variable of the object decision; When the compile-time type is inconsistent with the Run-time type, it c

the book to implement the two patterns is completely different (I think this implementation is somewhat arbitrary). the state mode, in particular, uses a separate implementation hierarchy, but I don't think it's necessary unless you assume that the implementation code is not controlled by you (which is, of course, a possibility, but if the code is controlled by you, It is also more concise and practical wi

DataInputStream (data input stream), source and example DataInputStream Introduction DataInputStream is the data input stream. It inherits from FilterInputStream. DataInputStream is used to decorate other input streams, which "allows applications to read basic Java data types from the underlying input stream in a machine-independent manner." Applications can use DataOutputStream (data output streams) to

intuitive as calling properties, in addition, the processing speed of XML files is less time-consuming than that of plain text files. However, if we use small relational databases such as access and sqllite to save the poor data, we will not be too busy with the public, and the loss will not be worth the candle. For example, my loonframework-game framework is a java2d game development component. Therefore, it should provide a persistent storage envir

Because of the project needs, and an insurance company docking call API, my company is the PHP background, the insurance company is Java background, the middle of the data transmission will not be able to encrypt, decrypt, the current encrypted AES comparison recommended. In the process of docking, it is inevitable to turn over the mountains, the more water, Here are the encryption instructions for my docking company: Be sure to know their own encry

seat to another with the help of an empty seat. If there are 4 plates, the first one is to move the three plates from a to B from a plate 1, to move the plate 1 to the c,a into the empty seat, and to move the three plates on block B to C with the help of empty seat C. The Java code is as follows: public class Hanoi {public static void Main (string[] args) { int disk = 3;//Plate move

The most basic Oracle database connection code (for oracle11g only):1, right-click Project, build path, configuration build path, select the third item "Library", then click "Add External Jar" and select "D:\Oracle\app\oracle\product\11.2.0\server \jdbc\lib\ Ojdbc6_g.jar "(Note: D:\Oracle is the installation path for the database).2. The following code is a very standard

This article records some code examples that use the annotations feature of the XStream API to convert Java objects to and from XML strings.Many of us have worked with XML files, and there are many very mature third-party open source software. such as:Jdom,dom4j and so on. Although they are very powerful, they are still a bit less accustomed to use. For a fixed-format XML document, its structure does not c

In Andriod development, a large part of the resources to deal with, such as: pictures, layout files, strings, styles and so on. This is a great difficulty for us to develop some common components, because common components may be more likely to be in the form of jar packs. However, only Java code is allowed in the Java JAR Package and no resources are available.
