advantages of anonymous class in java

In our usual development I want to use the most language is Java, was fortunate to buy the Java Core Technology volume a book, actually do not want to purchase, because they feel the foundation is also good, have read crazy Java handouts, Java programming ideas of these foundations, but also read

are commonly used in desktop applications.2. Lack of rich component features: The button does not support pictures.3. No extensibility: The components of AWT are local components. The AWT class instance in the JVM is actually just a reference to the local component. The only extension point is the AWT's canvas component, which creates a custom component from scratch. However, it is not possible to inherit and reuse an existing AWT componentSwingSwing

Software services development, there are a lot of development tools, then talk about the ultimate Java winning technology advantages:1.0 CapitalJava API is a valuable free asset compared to Java itself. Do you want to use the socket to operate the network? In the API, you want to connect to a SQL database? The API has; Do you want to give the app a nice user inte

Java is a widely used network programming language. With the development of Internet, the Java language has been used more and more widely with its strong vitality. The Java language is respected, because it really is a new generation of programming languages, with object-oriented, portable, and hardware-independent, system robust security, providing a concurrenc

global functions, and many other flashy places. In terms of inheritance, both adopt a single inheritance and multi-interface implementation scheme that is easier to understand and construct. In terms of source code organization, we have put forward a better logical encapsulation of declarations and implementations. In terms of the Type System, both languages have put forward the reflection concept based on the intermediate language il or byte code, this completely revolutionizes the traditional

, interfaces, and inheritance, and the Java Class (class) supports only single inheritance (c + + supports multiple inheritance), interfaces (interface) support multiple inheritance, and the implementation (implements) mechanism between classes and interfaces. Java is similar to Smalltalk on object-oriented, but better

Advantages and disadvantages of blocking and non-blocking Io packages in Java The cornerstone behind NiO design: the reactor model, which is used for event Multi-Channel Separation and dispatching of the architecture model. Reactor: an architecture pattern used for event Multi-Channel Separation and allocation Generally, a file or device specified by a file descriptor can work in two ways: blocking and non-

as if the file is already in memory. Using the virtual memory technology, the Java NiO method can quickly read large files. Java NiO opens a file to specify the location of the mapped content in the file you want to map. Open File source code using Java NIO: Import Java.io.RandomAccessFile; Import Java.nio.MappedByteBuffer; Import Java.nio.channels.FileChannel;

The application scenario of Java reflection mechanism and its advantages and disadvantages What is the applicable scene of reflection? 1). The Java reflection mechanism is useful when it comes to doing the basic framework, saying that the reflection mechanism is the cornerstone of many Java frameworks . And the genera

to six java files, and each method in the class is added, it also needs to add the corresponding code to its interface and other four java files. Day !!! I remember that at that time, my little finger often didn't listen, because I often used Ctrl + C, CTRL + V, and the little finger pressed the ctrl key to get tired. The entire project team is so miserable. Aft

In Java, reading data from the console is a common function. The implementation in versions earlier than JDK 5.0 is complex and requires manual processing of system input streams. Since JDK 5.0, every time a version number is added to the method that can input data from the console, there is a new method, which also adds the selected type, you can choose based on different requirements. Next, let's take a look at the methods for reading data from the

runnable class without creating a subclass of the thread. In most cases, if you only want to override the run () method, instead of other thread methods, you should use the runnable interface. This is important because you should not create a subclass for the class unless the programmer intends to modify or enhance the basic behavior of the class. Inherit the Th

The Java language has a rich history and is widely used by many programmers and businesses today, without questioning the results of Java's leading technology. Java is a programming language developed by Sun. Sun Company's initial direction is to let Java to develop some electrical installation procedures, such as: Set-top box, bus card, sun company never though

Recently, I am working on a framework for reading database metadata. The database check exceptions are impressive. Try-catch is crazy. At the same time, when exceptions in the framework should be thrown to the caller and which ones should be handled by themselves, check exceptions or non-check exceptions are worth pondering. Many of the following are my opinions. I hope you can add and point out the mistakes. Java philosophy: poorly structured Code ca

. There are two types of nesting classes. One is static (modified with the static keyword), and the other is non-static, it is called an inner class ). Note: in Think in Java, the author defines an internal class as "defining a class within the definition of another class, t

Entity Bean: Provides robust data persistence. The bean container handles most of the data integrity, resource management, and concurrency features, allowing developers to focus on business logic and data processing, rather than these low-level details. When using bean-managed persistence (Bean Managed persistence,bmp) entity beans, developers write persistent code and the container determines when the code executes. When using container-managed persistence (Container Managed Persistence, CMP) e

collected in different ways to improve the efficiency of recycling. In the course of running a Java program, a large number of objects are generated, some of which are related to business information, such as those in HTTP requests.Session object, thread, socket connection, such objects are directly linked to the business, so the life cycle is longer. However, there are some objects, mainly the temporary variables generated during the run of the prog
