What is Java?
Java is a universal, object-oriented, class-based programming language that has a few implementation dependencies as possible. The purpose is to enable application developers to write and execute once. This means that compiled Java code can be run on all platforms that support Java without having to recompile. Java applications are generally compiled into bytecode that can run on any Java Virtual Machine (JVM) regardless of the architecture of the underlying computer.
The original Java compilers, virtual machines, and reference class and implementation libraries were originally released by Sun under proprietary licenses. By May 2007, Sun had sublicensed most of its Java technologies under the GNU General Public License in accordance with the Java Community Process specifications.
At the same time, other alternative implementations of these Sun technologies have been developed, e.g. the GNU compiler for Java (bytecode compiler), the GNU classpath (standard libraries) and IcedTea-Web (browser plug-in for applets).
About the latest version of Java
The latest versions are Java 13, which was released in September 2019, and Java 11, a currently supported version (LTS), which is currently supported and was released on September 25, 2018. Oracle released the latest free public update for the Java 8 LTS legacy for commercial use in January 2019. Otherwise, Java 8 will continue to be supported with public updates for personal use until at least December 2022.
Oracle (and others) strongly recommend that you uninstall older versions of Java because of the serious risks associated with unresolved security issues. Since Java 9 (and 10 and 12) is no longer supported, Oracle recommends that users immediately upgrade to the latest version (currently Java 13) or an LTS version.
What are the major Java Versions?
As of March 2019, Java 8 version is still supported; and Java 8 and 11 as the Long Term Support (LTS) versions of Java.
Below are major release Java versions, along with release dates:
What are Java frameworks?
Frames or frameworks are large pieces/bodies of pre-written code to which you add your own code to solve a problem. You can use a frame by calling its methods, inheriting and providing callbacks, listeners, or other implementations of the models.
A Java framework often determines the structure of an application. Some Java frameworks even offer so much code that you only have to do very little to write your application. This can be good or bad depending on usability. Frames or frameworks are the substance of programming. It is based on a good program, is solid and fast and can be combined perfectly. You build on a bad one; your life is miserable, brutal and short.
Spring Framework is a powerful and lightweight application development framework used for Enterprise Java (JEE).
The main features of the Spring Framework can be used to develop any Java application. It is described as a complete modular framework. This Java framework is useable for all layer implementations of a real-time application. Unlike other frameworks, it can also be used to develop a specific level of an application in real-time. With Spring, however, we can develop all levels.
Google Web Toolkit [GWT]
Grails is a dynamic framework invented by the Groovy JVM programming language. It is an object-oriented language for the Java platform that aims to improve developer productivity. The syntax is Java compatible and is compiled in the JVM bytecode (Java Virtual Machine). Grails works with Java technologies including Java EE, Spring, SiteMesh, Quartz and Hibernate containers.
It is a responsive web and mobile Java framework for highly scalable Java applications. With Play, you can develop easy and user-friendly Java and Scala applications for the web and mobile interfaces. It is often compared to powerful frameworks from other languages, e.g. B. Ruby on Rails for Ruby or Django for Python.
Play is a unique Java framework because it is not based on Java EE standards. Instead, all the disadvantages of traditional Java web development such as slow development cycles, many configurations and much more are to be eliminated. Play Framework is based on the Akka Toolkit and cuts off the creation of simultaneous and distributed applications on the Java Virtual Machine.
The React framework created by Facebook quickly became more and more popular. It is used to develop and operate the dynamic user interface of websites with high incoming data traffic. It uses a virtual DOM and is, therefore, easier to integrate into any application.
The launch of Ember.js on the software market in 2015 has gained popularity with its wide range of applications. The functionality of Ember.js supports bidirectional data binding and thus creates a reliable platform for the administration of complex user interfaces. Popular websites such as LinkedIn, Netflix, Nordstrom and many others use the Ember.JS platform for their websites.
The Meteor application area (also known as Meteor.js or MeteorJS) bears the name itself because it varies because it covers almost most software developments. The uses of this framework include important areas such as core development, database management, business logic, and front-end rendering.

Object-oriented programming (OOP)
In both languages, the developer must mutually encode objects and their relationships. In detail, it enables the two languages to access techniques such as inheritance, encapsulation, and polymorphism.
Java is an object-oriented programming language and has a platform for virtual machines that you can use to create compiled programs that run on almost all platforms. Java promised: “Write once, execute everywhere.”

Programming Languages and Scripting Languages are quite different. One is used for Standalone Software development while the other goes for Web Applications.
