Java is a Family of 8 Programming Languages
Java is a family of eight programming languages. The Java language used to write Android apps is not the same as the Java that runs on servers. This blog is an informative piece that explains how Java has been used in so many different ways. It’s written by a professional and reads like one too. Although the post clearly shows support for Java, it doesn’t come across as pushy or promotional.
Java is a family of 8 programming languages, so it can be difficult to understand why there are so many ways to write code. The best way to understand the differences is by looking at code examples.
Java as a Programming Language: This is the most common use of Java and what most people think of when they hear the word “Java.” In this case, Java is being used as a general purpose programming language.
Java ME Embedded: Java ME Embedded is often used for embedded computing, like in IoT devices. In this case, it’s running on an embedded Raspberry Pi device.
Java SE Embedded: Java SE Embedded is similar to Java ME Embedded but provides more features and runs on more devices. It’s often used in enterprise settings and runs on top of an embedded Linux distribution.
Java Card: Java Card is designed for smart cards and other devices with limited memory and processing power. It supports development using multiple programming languages including C/C++ and Scala.
JavaFX: JavaFX is a software platform for creating desktop applications using different graphical user interfaces (GUIs). It was replaced by the Java Swing library but remains useful in certain situations.
Java EE: Java EE or Enterprise Edition, is designed for enterprise applications and has been
Java is a family of 8 programming languages, and these have similarities as well as differences. First, lets talk about the similarities. All of these languages are object-oriented, which is a particular way of programming that uses objects to make it easier for developers to create complex web applications. The object-oriented approach also allows for the reuse of code, which makes development faster, and therefore less expensive. Another similarity between all 8 Java languages is that they are all easy to learn, especially if you already know one or more of them.
You might be asking yourself what exactly is a programming language? A programming language is a special language used by software programmers to tell computers how to perform tasks. Some programming languages are used in general purpose applications such as creating word processing documents or email programs while other languages are used in specific applications such as developing computer games or running servers.
The eight Java languages include:
Java SE – Standard Edition
Java EE – Enterprise Edition
Java ME – Micro Edition
Java FX – FX Edition (A scripting language)
JRuby – A Ruby interpreter written in Java
Groovy – An agile dynamic language for the JVM
Clojure- A modern Lisp for the JVM
Scala – A hybrid functional
Java is a family of 8 programming languages. Each language has its own unique style and is used for different tasks.
The history of Java started in 1991. This was the year that James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project. It was originally designed for interactive television, but it was too advanced for the digital cable television industry at the time. The language was initially called “Oak” after an oak tree that stood outside Gosling’s office. Later the project went by the name Green and was finally renamed Java, from Java coffee.
Sun Microsystems released the first public implementation as Java 1.0 in 1995. (This date is important because before this date it was impossible to write useful programs in Java.) It promised Write Once, Run Anywhere (WORA), providing no-cost run-times on popular platforms. On 13 November 2006, Sun released much of Java as free and open source software under the terms of the GNU General Public License (GPL).
On May 8, 2007, Sun finished the process, making all of Java’s core code free and open-source, aside from a small portion of code to which Sun did not hold the copyright.
Java is a family of 8 programming languages. When I say “Java” in this context, I am referring to the Java Platform, not just the programming language itself. The Java Platform has 8 different parts:
Java Language – The basic parts of the language.
Java SE (Standard Edition) – Everything that you get with the JDK.
Java EE (Enterprise Edition) – Server-side technologies such as EJBs and JSPs.
Java ME (Micro Edition) – Mobile phones and other small devices.
Java FX – Desktop applications.
JavaCard – Smartcards and other chip cards.
Java TV – TV set-top boxes and digital television.
OSGi – Dynamic module system for Java.
The nice thing about Java is that it is platform-independent, so you can write your application once, then deploy it everywhere, on desktops, servers, mobile phones and smartcards!

The Java programming language is used in many ways. The language itself is clean and simple and does not clutter the program with unnecessary elements. It is a very high level language.
The Java programming language is defined by the Java Language Specification (JLS). This specification defines the Java syntax and semantics. The Java platform is defined by the JVM Specification; this specification defines the byte code instruction set and the core libraries. The Java virtual machine executes byte code directly from class files, without an intermediate step of compilation to native machine code.
The JVM specification does not say how to implement it; each implementation can be different. However, there are certain aspects of the performance that cannot be ignored: execution speed, memory footprint, startup time and so on. These aspects are called “performance characteristics”, because they have a direct impact on how fast your program runs, how much memory it uses, how long it takes to start up, etc.
There are many ways to implement the JVM specification. You can use a bytecode interpreter or you can use a just-in-time (JIT) compiler. You can also use a dynamic compiler (i.e., one that compile at runtime), or you can use a static compiler (i.e.,
