Difference between JDK, JRE and JVM

JDK	JRE
The full form of JDK is Java Development Kit.	The full form of JRE is Java Runtime Environment.
JDK is a software development kit to develop applications in Java.	It is a software bundle which provides Java class libraries with necessary components to run Java code.

Most program only need the JRE (Java Runtime Environment) but some programs need the Compiler at runtime in which case you need the JDK. If you have the JDK, you don’t need the JRE as well. To run a jar file you only need java.exe(windows). JDK is the development kit for Java and JRE is the runtime.

If you want to run Java programs, but not develop them, download the JRE. If you want to develop Java applications, download the Java Development Kit, or JDK. The JDK includes the JRE, so you do not have to download both separately.

In this release, the JRE or Server JRE is no longer offered. Only the JDK is offered. Users can use jlink to create smaller custom runtimes.

Staying with Java SE 8 Through at least December 2020 the Oracle JDK will remain free for personal desktop use, development, testing, prototyping, demonstrating and for use with certain types of applications.

Do you have to pay to use Java? No, not unless you want long-term support from Oracle. Starting with Java 11, Oracle provides two Java Development Kit releases, an OpenJDK build under the GPL open-source license and a commercial Oracle JDK build under a paid-for license.

Java code is maintainable. Compared to languages like C++, Java’s syntax is a great simplification; it lacks many features, customizations, and powerful constructs C++ has. At the same time, compared to scripting languages, Java has many “rituals” that are redundant at first glance.

Oracle owned Java will no longer provide free public updates of Java SE 8 for commercial use after January 2019. This move is a part of their long term support (LTS) plan. In most cases, the Java-based applications run on your PCs are licensed by a company other than Oracle.

There is no legal way to obtain a free, full copy of the Java edition of Minecraft; if you want the full version of Minecraft, you’ll have to buy it.

You can download java from http://java.com/en/. The legitimate java plug-in is safe to install, but some websites use fake pop-up windows to trick you into downloading software that isn’t actually java.

Try Minecraft for free! Play with your friends and embark on adventures complete with beautiful landscapes and sudden peril. The Minecraft free trial is available on Windows 10, Android, PlayStation 4, PlayStation 3, and Vita. Keep scrolling for the Minecraft: Java Edition free trial.

The latest version of Java is Java 16 or JDK 16 released on March, 16th 2021 (follow this article to check Java version on your computer).

Java SE 8 remains the preferred production standard in 2019. While both 9 and 10 have been released, neither will be offering LTS. Since it’s first release in 1996, Java has maintained a reputation for being one of the most secure, reliable, and platform independent languages for computer programming.

JDK 13 is the open-source reference implementation of version 13 of the Java SE Platform as specified by by JSR 388 in the Java Community Process. JDK 13 reached General Availability on 17 September 2019.

Java 13 will be released on 2019-09-17. It is not an LTS release and will be obsoleted at the release of Java 14 in March 2020.

Oak (programming language)

Java does not have any full form, but a programming language originally developed by James Gosling at Sun Microsystems in 1995. The developers of Java were drinking coffee while they were deciding the name of their programming language. JAVA means Coffee..

XML, in full extensible markup language, a document formatting language used for some World Wide Web pages. XML is a simplified form of SGML (standard generalized markup language) intended for documents that are published on the Web.

Extensible Markup Language (XML) is used to describe data. The XML standard is a flexible way to create information formats and electronically share structured data via the public Internet, as well as via corporate networks.

All XML elements must have a closing tag. XML tags are case sensitive. All XML elements must be properly nested. All XML documents must have a root element.

PHP originally stood for Personal Home Page, but it now stands for the recursive initialism PHP: Hypertext Preprocessor. PHP code is usually processed on a web server by a PHP interpreter implemented as a module, a daemon or as a Common Gateway Interface (CGI) executable.

PHP is a programming language for back end development only. JavaScript, in turn, was initially designed as a front end development language. But with the introduction of Node. The commonly cited claim that “JavaScript is only for front end development, and PHP is for back end” is just not true.

PHP is a server side scripting language that is embedded in HTML. It is used to manage dynamic content, databases, session tracking, even build entire e-commerce sites. It is integrated with a number of popular databases, including MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server.

Python is better in the long-term projects. PHP has a very low learning curve, and it is straightforward to get started with. Python uses indentation enforcements that are quite strict. This makes it more readable than PHP.
