The Java language has undergone several changes since JDK 1.0 as well as numerous additions of classes and packages to the standard library.Since J2SE 1.4, the evolution of the Java language has been governed by the Java Community Process (JCP), which uses Java Specification Requests (JSRs) to propose and specify additions and changes to the Java platform.
The performance of a Java bytecode compiled Java program depends on how optimally its given tasks are managed by the host Java virtual machine (JVM), and how well the JVM exploits the features of the computer hardware and operating system (OS) in doing so. Thus, any Java performance test or comparison has to always report the version, vendor ...
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile.

A 1.3 level Java runtime or Java development kit must be installed on the machine in order to run this version of Eclipse. [28] N/A: 18 September 2002 [29] 2.0 N/A: 15 April 2003 [30] 2.1 A 1.4 level Java runtime or Java development kit (JDK) can also be used to run Eclipse.
In computing, the Java Secure Socket Extension (JSSE) is a Java API and a provider implementation named SunJSSE that enable secure Internet communications in the Java Runtime Environment. It implements a Java technology version of the Secure Sockets Layer (SSL) and the Transport Layer Security (TLS) protocols .
Eclipse OpenJ9 embeds Eclipse OMR, which provides core runtime components that can be used to build runtime environments for different programming languages. At the OpenJ9 project, an extra layer of code adds the language semantics to provide a runtime environment for Java applications.
The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.
The platform was known as Java 2 Platform, Standard Edition or J2SE from version 1.2, until the name was changed to Java Platform, Standard Edition or Java SE in version 1.5. The "SE" is used to distinguish the base platform from the Enterprise Edition and Micro Edition platforms. The "2" was originally intended to emphasize the major changes ...
