There are many high level programming languages available for programmer for developing enterprise and general use applications. But Java is one of the most popular and widely used programming languages. Software companies are using along with other modern languages for building applications to run their business. Java came into existence as version 1.0 in January 1996. At that time its name was Oak programming language. Since then Java popularity is increasing and now it's one of the most used programming language.
Java is a popular programming language due its power and flexibility. If we see
the latest version of Java, JDK 15 then we can find many improvements and new
features in this release. Java 15 major features include records, text blocks,
new garbage collection algorithms, and more. It also adds new preview features,
including sealed classes and hidden classes. The JDK 15 is not a release
as long-term support version, but its support will end in the month of March
2021. After that Java 17 will be released, but it is again a short-term
supported version. Java 17 will be released after Java 16 as a long-term support
These changes and improvements in Java 15 will make Java a better programming language, which can be used by developers around the world for constructing their advanced applications. Java is used in developing applications for Banking, Finance, Social Network, Accounting, Mobile, Web and many enterprise applications. Its demand is very high in Job market.

Check our tutorials Java tutorials, How to learn Java with no programming experience?, How to learn Java? and Learn Java in a day. These tutorials will help you in getting started and learning Java Programming language.
Java programming language is platform independent and it can run on any platform having a JVM on it. You can compile your Java code on one platform, then you will be able to run many other operating system and platform. On the host platform the compiled Java byte code (that you distribute in jar file) is converted into the machine language by JVM and executed on the host platform. So, the import feature of Java is compile once and run anywhere, which gives a huge boot and developers can distribute their applications to many platforms after compilation. Check more detail about the JVM at our tutorial page Java Virtual Machine (JVM).
