Advance Java

What is Advance Java?

The dictionary meaning of advance is a forward movement or a development or improvement and the meaning of improve means thing that makes something better. All in all, we have to improve our basic knowledge to master in that particular field.

Java is divided into two parts i.e. Core Java (J2SE) and Advanced Java (JEE). The core Java part covers the fundamentals (data types, functions, operators, loops, thread, exception handling, etc.) of the Java programming language. It is used to develop general purpose applications. Whereas Advanced Java covers the standard concepts such as database connectivity, networking, Servlet, web-services, etc. In this section, we will discuss what is advance Java, its benefit, uses, topics of advance Java, and the difference between core Java and advance Java.

Advance Java

It is a part of Java programming language. It is an advanced technology or advance version of Java specially designed to develop web-based, network-centric or enterprise applications. It includes the concepts like Servlet, JSP, JDBC, RMI, Socket programming, etc. It is a specialization in specific domain.

Most of the applications developed using advance Java uses tow-tier architecture i.e. Client and Server. All the applications that runs on Server can be considered as advance Java applications.

Why advance Java?

It simplifies the complexity of a building n-tier application.

Standardizes and API between components and application sever container.

JEE application Server and Containers provides the framework services.

Benefits of Advance Java

The four major benefits of advance Java that are, network centric, process simplification, and futuristic imaging standard.

JEE (advance Java) provides libraries to understand the concept of Client-Server architecture for web- based applications.

We can also work with web and application servers such as Apache Tomcat and Glassfish Using these servers, we can understand the working of HTTP protocol. It cannot be done in core Java.

It is also important understand the advance Java if you are dealing with trading technologies like Hadoop, cloud-native and data science.

It provides a set of services, API and protocols, that provides the functionality which is necessary for developing multi-tiered application, web-based application.

There is a number of advance Java frameworks like, Spring, Hibernate, Struts, that enables us to develop secure transaction-based web applications such as banking application, inventory management application.

Difference between Core Java and Advance Java

Criteria Core Java Advance Java

Used for It is used to develop general purpose application. It is used to develop web-based applications.

Purpose It does not deal with database, socket programming, etc. It deals with socket programming, DOM, and networking applications.

Architecture It is a single tier architecture. It is a mute-tier architecture.

Edition It is a Java Standard Edition. It is a Java Enterprise Edition.

Package It provides java.lang.* package. It provides java.servlet.* package.
