A simple meaning of advance is improvement or development or moving forward so in the same context everything that goes beyond core java is advanced java. The major difference between core java and advanced java is core java is used for developing or creating a general-purpose application advanced java specifically deals with online application like mobile and website application.
It is part of the Java programing language. It mainly includes Application programming interface (API) like Servlet Programming, Web services, and persistent API and other concepts like java server pages(JSP), java database connectivity (JDBC), remote method invocation (RMI), socket programming, etc. Advanced Java is specifically designed to develop network-centric, web-based, or enterprise applications, or we can say it is specialization in a specific domain. Client and server architecture i.e. two-tier architecture is used in developing applications using advanced java. Hence applications that run on the server can be considered advanced java applications.
JDBC is an acronym used for Java Database Connectivity. It is an important concept of advanced java. The application programming interface for independent database connectivity between a broad scope of databases and java programing language is called JDBC. It enables users to approach request statements in a structured query language (SQL) which is later passed to manage databases. It generally entails opening a connection, generating a SQL database, carry out SQL queries, and then reaching the output. Users can update, delete, save and, fetch data from databases with the help of JDBC.
Both two-tier and three-tier processing models for databases are supported by JDBC API but architecture if JDBC consisted of two layers
Servlet is a language class of java programming. It is helpful to expand the capacity of servers that provide applications retrieved by means of a request-response programming model. In other words, it is a server-side technology in the java platform that answers a coming request from a browser client with a response. Although it responds to some type of request, it is commonly helpful to expand the applications provided by web servers. Key features of servlets can be described as follows
Java Server Pages (JSP) is like servlet technology that is used to create a web application. JSP provides more functionality than servlet such as expression language, JST, etc, and hence it also refers to as an extension to servlets. JSP consists of two tags HTML and JSP. It is easier to maintain JSP pages as we can separate designing and development. Some additional features like expression language, custom tags are also provided by JSP. Key features of JSP are as follows
Here comes the end of brief information on the advanced java tutorial. I hope it helps to clear basic questions in simple languages like what is advanced java, its components, and advanced java programming.
