Oracle (and others) "highly recommend that you uninstall older versions of Java" than Java 8, because of serious risks due to unresolved security issues. Java 11, both also currently supported LTS versions. Regarding Oracle, it distributes Java 8, and also makes available e.g. Distributions include Amazon Corretto, Zulu, AdoptOpenJDK, and Liberica. As an open source platform, Java has many distributors, including Amazon, IBM, Azul Systems, and AdoptOpenJDK. The latest version is Java 19, released in September 2022, while Java 17, the latest long-term support (LTS), was released in September 2021. On November 13, 2006, Sun Microsystems made the bulk of its implementation of Java available under the GNU General Public License (GPL).
Memory management is handled through integrated automatic garbage collection performed by the JVM.
all currently supported by Oracle, may use escape analysis optimization to allocate on the stack instead) and all variables of object types are references. Java eschews certain low-level constructs such as pointers and has a very simple memory model where objects are allocated on the heap (while some implementations e.g. Java syntax borrows heavily from C and C++, but object-oriented features are modeled after Smalltalk and Objective-C. In addition, several languages have been designed to run natively on the JVM, including Clojure, Groovy, and Scala. Writing in the Java programming language is the primary way to produce code that will be deployed as byte code in a Java virtual machine (JVM) byte code compilers are also available for other languages, including Ada, JavaScript, Python, and Ruby. Java applets, which are less common than standalone Java applications, were commonly run in secure, sandboxed environments to provide many features of native applications through being embedded in HTML pages. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers. Java is a set of computer software and specifications developed by James Gosling at Sun Microsystems that provides a system for developing application software and deploying it in a cross-platform computing environment.
