Web Application
Web applications is a distributed application that means they are programs which run on more than one computer and are able to communicate via a network or server.

Like desktop applications, web applications are also made up of many parts, and it mainly contains mini-programs. In addition, web applications regularly require an additional markup or scripting language, like – HTML, CSS, or JavaScript programming language. Many applications use only the Java programming language, because of its versatility.

JAVA WEB OR JAVA EE CONTAINER
Java web applications mainly not run directly on the server. Java web applications mostly run inside a web container on the server. This container provides a runtime environment for Java web applications. The container itself runs in the Java Virtual Machine. In general, Java differentiates two containers: the web container and the Java EE container. A web container supports the performance of JavaServer Pages and Java servlets. Java EE container supports additional functionality like – distribution of server load. Most modern Java web frameworks are based on servlets. Nowadays the popular Java web frameworks are JavaServer Faces, GWT, Struts, and the Spring framework. These web frameworks mainly require a minimum web container.
JAVA WEB APPLICATION
Java web application is a collection of vibrant resources, like – JavaServer Pages, Servlets, Java classes and jars with static resources, like -HTML pages and pictures.

Java language is used in an array of computing platforms, like – mobile phones, embedded devices, enterprise servers, and supercomputers. Nowadays there are lots of Java tools available in the market which helps to improve the efficiency of Java developers. So the developers become capable of designing products and Java applications with better functionality.
