What are the different java technologies?
There are several types of Java technology. Some examples of Java software are Java ME, Java EE, Java SE, and Java Card. Java made the JAVA development kit for those that develop in Java. There is also Java Virtual machine and some class libraries. Java is also famous for its languages like Clojure, Beanshell, Groovy, Gosu, Rhino, Kotlin, JRuby, Scala, and Jython.
What is java jre and java jdk?
== == JRE includes (JVM ) java virtual machine and some other library files. That runs a java application. JVM - understand the corresponding byte code of a java class and make it ready for run. The Java Runtime Environment (JRE) is an implementation of the JVM (Java Virtual Machine) that actually executes our java programs.The Java Virtual Machine (JVM) is created, like a separate program, whenever a java program is executed. The JVM essentially runs between the computer and the java program. Java is designed so that any java program can run on any machine. This is because the JVM will interpret the Operating System independent java code and execute the commands needed for the particular Operating System you are trying to run the program on at the time.Java Program --- Execute some command ---> JVM --- Translate the command for this computer ---> ComputerJava Virtual Machine (JVM) A Java Virtual Machine (JVM) is a set of computer software programs and data structures that use a virtual machine model for the execution of other computer programs and scripts. The model used by a JVM accepts a form of computer intermediate language commonly referred to as Java bytecode. This language conceptually represents the instruction set of a stack-oriented, capability architecture. As of 2006, there are an estimated four billion JVM-enabled devices worldwide. Java Runtime Environment contains JVM, class libraries, and other supporting files. It does not contain any development tools such as compiler, debugger, etc. Actually JVM runs the program, and it uses the class libraries, and other supporting files provided in JRE. If you want to run any java program, you need to have JRE installed in the system
What was Jython first developed for?
Jython was first developed to replace 'C' with 'Java'. It is a cross-platform operational system, combining both Python and Java. Jython can use and/or import any Java class around.

What is python not as in snake and what does it do?
Python is a programming language. On the python.org website, it is described as:Python is a remarkably powerful dynamic programming language that is used in a wide variety of application domains. Python is often compared to Tcl, Perl, Ruby, Scheme or Java. Some of its key distinguishing features include:very clear, readable syntaxstrong introspection capabilitiesintuitive object orientationnatural expression of procedural codefull modularity, supporting hierarchical packagesexception-based error handlingvery high level dynamic data typesextensive standard libraries and third party modules for virtually every taskextensions and modules easily written in C, C++ (or Java for Jython, or .NET languages for IronPython)embeddable within applications as a scripting interfaceIf you're looking to start programming, it's a very friendly introductory language to start with.
What are the various programming languages?
There are tons of programming and/or scripting languages throughout history to present. Some of these programming languages have been deprecated, some are just jokes, and several are commonly in use today.Alphabetical listing.* ActionScript (Flash)* Ajax * Algol * APEX* APL (developed in 1960s)* Basic* C/C++ (developed in 1980s)* C# * CGI * CFML - Coldfusion* Cobol (developed in 1950s)* CSS * Curl * Delphi * DHTML* Fortran (developed in 1950s) * GML (Game Maker Languages - for the Game Maker software) * MATLAB* HTML * HyperTalk - Apple Script* Intercal* Java/JavaScript * JSON* Jython* LaTeX * LISP (developed in 1950s)* LOLCode (a joke - scripting in IM-txt-speak)* .NET * Objective-C* Pascal * Perl * PHP * PostScript * Python * Ruby * Smalltalk* Snobol* SQL * VBScript * Visual Basic * XML * XSSSee the link below for a larger list from Wikipedia which still doesn't even contain all of the languages out there, but does contain a lot of them along with their dates of development. There are more computers in the world than just PCs (Personal Computer), such as mobile devices, calculators, console gaming systems, and various other electronics all have computers which contain a programming language to make them function the way they were intended.C#,Java,Flash(ActionScript),C/C++,.NET,and CSS.
