OpenJDK (Open Java Development Kit) is a free and open-source implementation of the Java Platform, Standard Edition (Java SE). [2] It is the result of an effort Sun Microsystems began in 2006, four years before the company was acquired by Oracle Corporation .
Oracle JDK 1.8.0_311, 11.0.13, 17.0.1 OpenJDK 1.8.0_312, 11.0.13, 17.0.1 The GraalVM distributions for Java SE 17 became available for download. The release added a new Infeasible Path Correlation optimization to eliminate infeasible paths, provided an implementation for Constant Blinding to defend against JIT spraying attacks.
Note that Java EE runs on the standard Java SE JVM but that some vendors specialize in providing a modified JVM optimized for Java EE applications. Much Java development work takes place on Windows, Solaris, Linux, and FreeBSD, primarily with the Oracle JVMs. Note the further complication of different 32-bit/64-bit varieties.

It is derivative of the community driven OpenJDK which Oracle stewards. [5] It provides software for working with Java applications. Examples of included software are the Java virtual machine, a compiler, performance monitoring tools, a debugger, and other utilities that Oracle considers useful for Java programmers.
The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A Java platform includes an execution engine (called a virtual machine), a compiler and a set of libraries; there may also be additional servers and alternative libraries that depend on the requirements.
However, newer JVM releases, such as the OpenJDK HotSpot JVM, support 64-bit architecture. Consequently, you can install a 32-bit or 64-bit JVM on a 64-bit operating system. The primary advantage of running Java in a 64-bit environment is the larger address space.
