Java is a programming language whose role is to help people solve problems encountered in daily work, life and study by writing applications.
##Java is also known as a language that can be used across platforms. This is mainly because after Java itself is compiled, it is not Instead of directly generating executable code, an intermediate code called ByteCode is generated. This code must be interpreted through a Java interpreter before it can actually be executed. It doesn't matter at all what platform the Java program was compiled on. Programs written in Java can be divided into two categories, namely Java Applet and general Application. The Application category is similar to general programs such as C and is an independent executable Applications, such as HotJava, are browsers developed using Java programs.
The most common Java programs include applications and applets. Applications are separate programs, such as the HotJava browser software, which is written in the Java language.
Applets are similar to applications, but they cannot run independently. Applets can run in a browser that supports Java. Applets are mainly built into HTML web pages and play a role during browsing.
The goal of Java is to develop software in a network environment full of various types of machines and different operating system platforms. Using Java programming language, you can add a variety of dynamic effects to web pages. You can put an animation, add sound, or create interactive web pages, etc.
Java technology’s openness, security and huge social resources, as well as its cross-platform nature, that is, the “write once, run anywhere” feature, make Java technology the de facto standard for smartphone software platforms .
After using Java technology, people who write applications and provide services do not need to care about what operating system and chip the mobile phone that receives its services uses. They only need to write programs according to the requirements of Java; you can see It turns out that using Java technology, a complete and efficient wireless data value-added service industry chain can be established, thereby providing users with flexible, personalized, and diverse services.
