As we have said, Java has compiled many classes for programmers that have been tested and basically without errors, and these classes are the basis of our programming. If we don't take advantage of these existing classes, our programming will become extremely complex, so we should master the contents of the Java base Class library as much as possible. This chapte

The JNA (Java Native Access) Framework is an open-source Java framework developed by SUN and built on the basis of the classic JNI. Very powerful and easy to use, similar to. net p/Invoke.You only need to download a jar package and use the powerful functions of JNA to conveniently call the C function in the dynamic link library. Download jna. jarDownload the late

The lambda expression is described earlier, but we can see that the lambda expression actually simplifies the writing of a part of the code and is not a very useful language feature. But if the lambda expression fits into the Stream class library described in this article, it will play a huge role. initial knowledge of flow class library As usual, let's take a look at an

Introduction to Java Basic class library A common base Class library: 11 Jar (Java Archive,java archive) packageAs a Java language user, we can feel the advantages of the Java language

I think any book about the mode can't help but mention its practical application when talking about the decorator mode-applications in the Java/IO library, I. Introduction (General Introduction to Java I/O) Regardless of the programming language, input and output are an important part. Java is no exception, and

with a log service abstraction layer, based on which you can choose different log implementations, For example: java.util.logging,logback,log4j, when you need to change the log implementation component, do not need to modify any code, just need to change some of the corresponding configuration. (code base on GitHub)2. Apache log4jLog4j is the most famous log component, which can easily be recorded in the program by simple configuration, and its log f

These examples can only bring us to know how to play the library and call steps, in the actual project process, encounter

The security vulnerability in the Java reflection library was fixed 30 months later. On June 25, July 2013, Security organization Security Events discovered a Security vulnerability in Java 7u25, which allows attackers to completely get rid of the Java sandbox. Oracle included a patch in the updated 7u40, but according

Lambda expressions are a core feature of Java SE 8, and most of the improvements are spread around lambda expressions. (The jigsaw project has been postponed to Java SE 9.) The contents of the lambda expression are described in the previous article. This article focuses on enhancements to other Java standard libraries that are included in

full name, or use the Import keyword in conjunction with mypackage (using the options given earlier). Note that according to the Java Package (encapsulation) Convention, all letters in the name should be lowercase, even in the middle words.For example, suppose the filename is Myclass.java. It means that there is one and only one public class in that file. And the name of that class must be MyClass (includi

These two days to understand the Java call DLL Dynamic library method, there are three kinds: JNI, JNA, jnative. Where the JNA call DLL is the most convenient.· Jni· JNA· JnativeJava uses JNI to invoke DLL dynamic library calls, the workload is slightly larger, in general, developers will choose JNA or jnative.Calling a DLL with Jnative requires an additional DLL
