Java was steadily on the top from mid-2015 to early 2020.

Java 8, 11, and 17 are previous LTS versions still officially supported. Oracle offers its own HotSpot Java Virtual Machine, however the official reference implementation is the OpenJDK JVM which is free open-source software and used by most developers and is the default JVM for almost all Linux distributions.Īs of September 2023, Java 21 is the latest version, which is also a long-term support (LTS) version. As of May 2007, in compliance with the specifications of the Java Community Process, Sun had relicensed most of its Java technologies under the GPL-2.0-only license.
The original and reference implementation Java compilers, virtual machines, and class libraries were originally released by Sun under proprietary licenses. It was released in May 1995 as a core component of Sun Microsystems' Java platform. Java was originally developed by James Gosling at Sun Microsystems. Although still widely popular, there has been a gradual decline in use of Java in recent years with other languages using JVM gaining popularity. Java was the third most popular programming language in 2022 according to GitHub and it is ranked fourth on TIOBE index as of October 2023. Java gained popularity shortly after its release, and has been a very popular programming language since then.
The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. It is a general-purpose programming language intended to let programmers write once, run anywhere ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible.
