In multithreaded programming, the more important and more difficult operation is how to get the information in the thread. One way most people will take a more common approach is to store the results returned in a thread in a field, and then provide

Most application performance management (APM) solutions only consider and analyze performance issues at one level of the Java application. This approach is not sufficient to address the performance problems of architecture-complex applications. A

Unit testing as a guarantee of software quality and reconstruction of the foundation, has long been recognized by the broad masses of developers. Unit testing is a fine-grained test in which more and more developers submit unit tests while

Historically, the Java™ platform has been the domain of object-oriented programming, but now even staunch supporters of the Java language are starting to notice a new trend in application development: Functional programming. In this new series, Ted

Specific domain language (domain-specific languages,dsl) has become a hot topic; Many functional languages are popular, mainly because they can be used to build DSLs. In view of this, in the final article of the Scala Guide series for Java

This article is the second part of the Java.next series. In this section, let's look at how the Java.next language interoperate with Java. In all of these java.next languages, it's easy to interoperate with Java. This is thanks to the Java Virtual

Java and XML is a combination of gold, there are many articles on the Internet, XML as a data exchange in E-commerce, has its irreplaceable role, but in peacetime system development, we do not necessarily have to use data exchange, is not the use of

I want to write a program in Java: How to lock the keyboard and mouse under the Java operation? That is, the client user is not allowed to make any input, the server side sends the message to unlock! Write a section of Java code so that the keyboard,

Although traditional assertions can increase the number of checks on Java code, there are still a number of checks that cannot be completed. One way to handle this situation is to use temporal logic. Recall last month's article "assertions and

Empty flag Error Mode In my last article, I explained how the use of NULL pointers in place of different basic types of data is one of the most common causes of nullpointerexception anomalies. This time, I will explain how an empty pointer instead

Write once and run anywhere. This is a promise, but the Java language can sometimes not do it. Admittedly, the JVM has raised the level of cross-platform interoperability to unprecedented heights, yet a small flaw in the specification and

J2SE 1.5―, code-named Tiger, is scheduled to be released by the end of 2003 and will include generic types (as shown in advance in the JSR-14 prototype compiler, which is now available for download). In part 1th, we discussed the basics of generic

Jiangnan white dress in September 2005, on his blog put forward: Each team should have a appfuse-style project to demonstrate the team's current system framework and design patterns. There are a dozen benefits to this project: providing common

One of the latest trends in programming, especially in Java programming, is the use of meta data. Simply put, metadata is data about data. Metadata can be used to create documents, track dependencies in code, and even perform basic compile-time

In this section, we introduce a relatively simple but powerful pattern: Observer mode. Hope that through this part of the narrative, we have seen, can have a more comprehensive design model, perceptual understanding. Often, experience is critical

Virtual Proxy is a memory-saving technique that suggests creating objects that consume large amounts of memory or deal with complexity by delaying the creation of such objects until they are used. In a particular application, the functions of

Three. Information Driven Beans Introduction Asynchronous messages can also be implemented by message-driven beans. In the EJB 1.1 specification, two types of EJBS are defined. are entity beans (Entity beans) and session beans. The client is

Almost all stylish apps have a welcome screen. The Welcome screen is one of the ways to promote the product, and during the long application startup process, the Welcome screen is also used to indicate that the application is in the process of being
