Java ME was formerly known as Java 2 Platform, Micro Edition or J2ME. The platform uses the object-oriented Java programming language, and is part of the Java software-platform family. It was designed by Sun Microsystems (now Oracle Corporation ) and replaced a similar technology, PersonalJava .
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 Java virtual machine is an abstract (virtual) computer defined by a specification. It is a part of the Java runtime environment. The garbage collection algorithm used and any internal optimization of the Java virtual machine instructions (their translation into machine code) are not specified. The main reason for this omission is to not ...

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. The primary reference Java VM implementation is HotSpot , produced by Oracle Corporation and many other big and medium-sized companies (e.g. IBM , Redhat ...
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.
MicroEmulator (also MicroEMU) — is a free and open-source platform independent J2ME emulator allowing to run MIDlets (applications and games) on any device with compatible JVM. It is written in pure Java as an implementation of J2ME in J2SE. [4] [5] [6]
Java Quick Starter reduces application start-up time by preloading part of JRE data at OS startup on disk cache. [27] Parts of the platform needed to execute an application accessed from the web when JRE is not installed are now downloaded first. The full JRE is 12 MB, a typical Swing application only needs to download 4 MB to start.
