Java is a programming language, which has surpassed the simple programming language in continuous development. Java mainly includes virtual machine environment, classes and supporting software, which can be well used in various operating systems.
Jade Bird of Henan Beida discovered that Java technologies mainly include JavaSE, JavaEE and JavaME.
Java has a wide range of applications and uses different methods. If you are a Java developer, you need to know better what field you are in, so that you can get better development in the study of software development.
Java has always been a widely used programming language, and it has exceeded the sum of many scripting languages in its use. Java's platform supports programs that can be run by different scripting languages, which means that numbers can overlap.
In many cases, these applications can run well, and Henan computer training found that the code can be optimized again.
Java is the preferred language development platform for many large enterprises, and its usage has been increasing. Java can provide free services for developers. In many universities, Java is also the preferred learning language. Although Java is widely used, there are still some problems in the use process. We should examine these problems correctly, which will be of great help to the future development.
Other supported languages: The Java platform supports applications written in different languages.
Henan java training found that more language support will be added now, including support for dynamic languages.
This is called Leonardo da Vinci or multilingual virtual machine.
In particular, the JVM has increased its support for dynamic languages, so it takes a lot of effort to increase its support for more languages.
Before that, the Java compiler needs extra coding to have a correct impact on the static requirements of the Java language.
With the support of dynamic language, JIT compilation time increases, which is much larger than normal memory consumption, thus increasing the amount of garbage collection.
It has been enhanced in JavaSE, and the existing bytecode can be modified during running, so it will consume less persistent space and reduce the times of garbage collection.
In the process of using JIT, Henan computer training suggests that more compiled codes can be optimized.
