What Is Java?
Java is a high-level programming language that came into light in 1955 and earlier known as “Oak” and “Green” during initial development. It brought the idea of C and C++ making all the developers easy to code and the main idea behind it was write once run anywhere, Instead of compiling to separate executables for different target platforms, Java source code is bundled in a single JAR file that runs on any all the system, which made java platform independent. Java runs on both virtual machines and web browsers too.
All the works done in Java is possible through Java Virtual Machine (JVM). The JVM finds the JAR record (which is a collection of Java-explicit guidelines), and then the JVM compiles the jar file to the platform-specific instructions at runtime, then the app is executable.
Java in the real world
- Android apps — Android was built using Java so it is the official language that can be used for Android app development making it more fastest in performance and native experience.
- Desktop apps — Java is available for a desktop app too. Using multiple plugins and frameworks java can be served for desktop applications too.
- Enterprise systems — With the availability of high and secure technology java is very much popular for web application building enterprise systems. Making all the industries and banks for enterprise, HR, banking system java is available for all.
- Embedded systems —Unlike desktop, mobile, and web app Java is applicable for embedded systems too like digital watches, controllers and traffic lights and etc.
