Introduction To Advanced Java

In the world of coding and software development, Java is one of the most used programming languages. It allows the creation and development of several different applications that can run on a single machine. Java is still popular among many developers and programmers as it has completed its 25th anniversary in 2020, and achieved a range of development in its programming efficiency for decades. It has evolved as a language of facts and practical knowledge. It is also known as the most prominent language for building robust web applications and technical platforms.

Java is so popular that several Fortune 500 organizations such as Google, LinkedIn, Facebook, Amazon, Apple, etc are using Java for their programming tasks. In fact, Java was ranked at the top in the list of the most in-demand programming languages of 2019 by Indeed. So it is clear that there is still a high demand for Java experts. Therefore many people search for appropriate training such as Advanced Java training in Hyderabad, Bangalore, etc. that can help them learn advanced Java and start a successful career in this domain. These training courses can help you learn about all the basic principles and advance knowledge of  Java. They cover the whole spectrum of Java programming to help you master Java and explore your potential of technical programming skills. 

 

In this article, we will try to focus on the introduction to Advanced Java.

Advanced Java Explained 

Basically, Advanced Java is a part of the Java programming language that is specially designed to develop web-based, network-centric, and enterprise applications. It is an advanced technology of Java that includes topics like JSP, Servlet, JDBC, Socket Programming, RMI, etc. These topics are specialized versions in specific domains. 

 

Advanced Java is everything that goes far further than Core Java. It is also known as a web and enterprise application development program that follows server and client architecture. Applications that are developed through Advanced Java uses two-tier architecture – Client and Server and all the applications that run on servers are considered advanced Java applications. 

Components of Advanced Java- Advanced Java, as a part of Java programming language, mainly involves API (Application programming interface) like Web services, Servlet Programming, persistent API, and other sectors such as JSP ( java server pages), JDBC (Java database connectivity), RMI (remote method invocation), socket programming, etc. Let us know about some features of advanced java.

 

  • JDBC- JDBC is known as a standard Java API for database-independent connectivity between a wide range of databases and the java programming language. It is a crucial part of the advanced java concept. It enables users to approach request statements in a SQL (structured query language) that is used to manage databases. Basically, it includes opening a connection, building a SQL database, executing SQL queries, and then reaching the output/result. It supports two-tier and three-tier processing models for database access. JDBC architecture consists of two layers: JDBC API and JDBC Driver API. Components of JDBC are Driver, Connection, and Driver Manager. 

 

  • Java Servlets- It is known as the language class of java programming that is used to extend the capabilities of servers that can host applications accessed through a request-response programming model. It is a server-side technology of the Java platform that answers a request from a browser client with a response. Basically, Java Servlet is used to build web applications and it is a must implement the interface for creating a servlet. It works as an API that offers many classes and interfaces that involve documentation. Some steps to create Servlet are: Create a directory structure, create a servlet, compile a servlet, add mapping to web.xml file, start the server and deploy the project and access the servlet. 

 

  • JSP- JSP refers to Java server pages, is a technology that is used to build web applications like servlet technology. It offers more functionality than servlets like JST, expression language, etc so it is referred to as an extension to servlets. It mainly consists of two tags JSP and HTML. JSP is easier to maintain as it enables separate design and development. It provides us with some unique features like custom tags, expression language, etc. JSP is portable, easy, and provides fast development. It is powerful, flexible, and can track the users. 

 

Let us now go through some of the advantages of Advanced Java.

Advantages of Advanced Java

 

  • Advanced java refers to JEE (Java Enterprise Edition) that provides a library to understand the client-server architecture for web application development that core Java doesn’t support. 
  • Advanced Java offers several frameworks such as JSF, Spring, Hibernate, Struts that enable you to develop secure transaction-based web apps for domains like E-commerce, finance, banking, healthcare, inventory, legal, etc. 
  • Advanced Java helps you to understand advanced technologies like Hadoop, data science, and cloud-native services.
  • Advanced java simplifies the difficulties in creating n-tier applications.
  • JEE Application Server and containers offer advanced framework services.
  • It standardizes an API between components and application server containers. 
  • Advanced Java can work with Glassfish and Apache Tomcat that can help understand HTML protocol which can not be done with core Java. 
  • Advanced java offers a set of protocols, API, and services that provides the functionality which is important for developing multi-tiered applications and web-based applications. 

Advanced Java Training Courses-  Advanced Java requires specialized educational and practical knowledge to learn the concepts of this subject. There are several advanced java courses available that you can opt for and land your career as an advanced java expert. These training courses help you gain in-demand skills and make you learn how to create applications with Java using the latest tools and techniques. Almost all the certification providers have industry experts as trainers who provide you with resources, coding exercises and training to help you increase your knowledge. So start preparing today if you want to explore your expertise in this highly advanced domain.
