Standard uses of java: 

We hear tons about the programming languages and their productivity. Java is one of the most popular and widely used languages. The people that belong to technology and programming understand the meaning and use of such languages. The other people are confused; do computers or software communicate employing a language? It is important to clarify the myths and confusions for the people. The software and programs we use on computers, tablets, phones and other devices are not solid but codes. There are certain binary and digital codes that seem to be graphics and different products for us. To form these codes, we'd like to possess languages like Java. 

 

Developing scientific applications  

Many people limit the potential of Java to programming applications only. It is interesting to understand that a lot of the scientific applications like MATLAB are technology based and made up of Java. The language helps to affect the scientific data easily. It exposes opportunities for the researchers to seem into matters with a special view. It is great with the mathematical calculations and probability tests results also . Using the info language helps these apps to process information easily. 

A scientific application is an application that affects real-world activities using mathematics. Java supports the development of scientific applications, because of its powerful features. 

 

• Java becomes the best choice for writing scientific applications involving scientific calculations and mathematical operations. It provides a fast, secure and highly portable environment to these applications, which is the basic requirement for these applications. 

• It has powerful mathematical calculations which have to give the same results on different platforms, this makes the choice for the developers to opt Java for scientific applications. 

• MATLAB (Mathematical Laboratory) which is one of the most popular scientific applications, uses Java for developing both front-end (interactive user-interface) and back-end (a core part of the system). 

• The front-end and back-end of the scientific applications are both based on Java. For the front-end, Java provides struts, JSP (Java Server Pages), servlets. For the back-end, core Java can be used in servlets. 

Examples of scientific applications are applications related to research, science, medical science, space, aeronautics, etc 

 

Desktop GUI App 

A Java GUI application uses the standard Java components GUI component set, Swing, and is deployed to the desktop. The Swing GUI Builder in NetBeans IDE simplifies the GUI development process and enables you to visually create Java GUI applications using pre-installed Swing and AWT components. 

JavaFX is a rich set of graphics and media packages that enables developers to design, create, test, debug, and deploy rich client applications (RIAs) that behave consistently across multiple platforms. 

 

Many of the software packs for the desktop GUI App are supported JavaScript. The language has some well-packed and sustainable options like JavaFX, Swings and AWT as mentioned above. Using these high-end options, it's easier for the developers to figure out complicated and check out parts. The packs with numerous features make the job easier, quick and efficient at the same time. 

 

Web pages and applications:- 

It is not almost the heavy profile development but the online pages and web-based applications aren't an enormous deal for Java. Using the resources and codes, it's quite easy to make sustainable sites, applications and pages. Many of the leading business sites, entertainment pages and other heavy profile sites are supported by JavaScript. The language has the potential to form each part of an internet page exclusively and run smoothly. For the heavy sites, the developers require strong backup that helps to stay the location running. 

 

A web application is a client-server program that is delivered on the Internet through a browser interface. 

• Java supports the development of web-applications with the help of servlets, struts, JSP (Java Server Pages) and JSF (Java Server Faces), Spring, Hibernate and web-servers like Apache Tomcat, Apache HTTP web-server, Resin, adobe JRun, etc. 

• With the help of these technologies, we can develop any kind of web-based application. 

• Servlets and JSPs are the server-side components that help to develop the business logic of the web application. JSP is an extension of the Servlet as it has more features as compared to the servlet. 

• E-commerce web applications also use Java with the help of open-source eCommerce platforms, such as Broadleaf. 

• Java provides easy coding and high security which enables the development of a large number of applications for health, social security, education, and insurance. 

Examples of web-based applications are irctc.co.in, online forms, shopping carts, Gmail, Google Sheets, Google Slides and many more. 

Enterprise  development 

An enterprise application is a large software system which operates in a corporate environment, to satisfy the requirements of an organization, instead of individual users. 

Java becomes the first choice for the development of enterprise applications because of its robust features that match the requirements for the same. In today’s era, most of the enterprise organizations are based on the applications of Java only because it is the most secure, powerful, scalable language. Oracle Corporation claims that “about 97% of enterprise applications use Java for development of large-scale software”. Java EE (Java Enterprise Edition) is an API that is used to provide the tools necessary to develop large-scale, multi-tiered, scalable, reliable, distributed and secured network applications in enterprises. 

• Java fulfills the most essential need of these enterprises, which is security, as Java runs inside the JVM (Java Virtual Machine), which verifies the bytecode coming from the external systems, which ultimately prevents the security breaches. This is the reason why most banking applications are developed on the Java platform. 

• Moreover, Java improves the performance of these applications, as it comes with strong memory management, which automatically deletes the unused memory. 

• Applications of Java can easily be made scalable in order to increase the number of users on the enterprise application site. 

• Companies like Naukri, Jabong, Google, Myntra, Flipkart, Trivago, ibibo, TripAdvisor, Spotify, Uber, TCS, Infosys, HCL, Wipro, Pinterest, eBay, etc use Java. 

Examples of enterprise applications are Business corporations, schools, banks, ERP (Enterprise Resource Planning) and CRM (Customer Resource Management) systems, clubs, charities, governments, interest-based user groups, etc. 

Tiered Applications:- 

In a multi-tiered application, the functionality of the application is separated into isolated functional areas, called tiers. Typically, multi-tiered applications have a client tier, a middle tier, and a data tier (often called the enterprise information systems tier). The client tier consists of a client program that creates  requests to the middle tier. The middle tier is divided into a web tier and a business tier, which handle client requests and process application data, storing it in a permanent datastore in the data tier. 

Java EE application development concentrates on the middle tier to make enterprise application management easier, more robust, and more secure. 

1. The Client Tier 

The client tier consists of application clients that access a Java EE server which are usually located on a special machine from the server. The clients make requests to the server. The server processes the requests and returns a response back to the client. Many different sorts of  applications are often Java EE clients, and that they aren't always, or maybe often Java applications. Clients are often an internet browser, a standalone application, or other servers, and that they  run on different machines from the Java EE server. 

 

 

2. The Web Tier 

The web tier consists of components that handle the interaction between clients and the business tier. Its primary tasks are the following: 

• Dynamically generate content in various formats for the client 

• Collect input from users of the client interface and return appropriate results from the components within the business tier 

• Control the flow of screens or pages on the client 

• Maintain the state of data for an user's session 

• Perform some basic logic and hold some data temporarily in managed beans 

3. The Business Tier 

The business tier consists of components that provide the business logic for an application. Business logic is code that gives functionality to a specific business domain, just like the financial industry, or an e-commerce site. In a properly designed enterprise application, the core functionality exists within the business tier components. 

The following Java EE technologies are among those that are used in the business tier in Java EE applications: 

• Enterprise JavaBeans (enterprise bean) components 

• JAX-RS RESTful web services 

• Java Persistence API entities 

 

Big Data technologies 

Java is the reason why the leading Big Data technologies like Hadoop have become a reality and also the most powerful programming languages like Scala are existing. It is crystal clear that Java is the backbone when it comes to developing Big Data using Java. 

Big Data Technology can be defined as a Software-Utility that is designed to Analyse, Process and Extract the information from extremely complex and large data sets which the Traditional Data Processing Software could never deal with. 

 

 

 

Mobile apps   

Developing a mobile app with the help of Java is quite easy. The cross platform language helps you to have the applications for all the Java supported devices including smartphones and tablets. Almost all the applications you are using on your smartphone are build-using JavaScript as the basic language. The resources and possibilities of language made it easier for the developers to possess the simplest productions. 

App servers and web servers 

It is amazing to understand that a lot of the app servers and web servers are Java web servers and app servers. The languages have potential to supply great sustainability and support for this server programming. These are the leading business and resource servers that are helping a variety of online businesses to sustain and grow online.
