What is Advanced Java, exactly?
The dictionary definition of advance is forward movement, development, or improvement, while the definition of improve is something that improves something. Overall, we must strengthen our fundamental understanding in order to master that particular field.
Core Java (J2SE) and Advanced Java are the two sections of the Java language (JEE). The principles of the Java programming language (data types, functions, operators, loops, threads, exception handling, and so on) are covered in the core Java section. It’s used to create general-purpose software. Advanced Java, on the other hand, includes standard principles like database connectivity, networking, Servlet, web services, and so on. In this section, we’ll look at what advance Java is, what it can do for you, what it can do for you, what it can do for you, what it can do for you, what it can do for you, what it can do for you, what it can do for
Java is more advanced.
It is a Java programming language feature. It is a web-based, network-centric, or enterprise application development technology or version of Java that is specifically designed for developing web-based, network-centric, or enterprise applications. It contains ideas such as Servlet.
, and JSP
, RMI, JDBC
, Programming using sockets
, and so on It is a domain-specific specialty.
The majority of advanced Java programmed have a two-tier architecture, i.e. Client and Server. All advanced Java applications that operate on the server can be classified as such.
Why should Java be improved?
It reduces the complexity of developing a multi-tier application.
The API between components and the application server container is standardized.
The framework services are provided by the JEE application server and containers.
Advantages of Advanced Java
Network centricity, process simplification, and a futuristic imaging standard are the four primary advantages of advanced Java.
JEE (advanced Java) includes modules that help you grasp the Client-Server architecture for web-based applications.
We can also work with Apache Tomcat and Glassfish, which are web and application servers. We can learn how the HTTP protocol works by using these servers. It’s not possible in core Java.
If you’re working with trade technologies like Hadoop, cloud-native, or data science, you’ll also need to know advanced Java.
It provides a set of services, APIs, and protocols that give the capability required to construct multi-tiered and web-based applications.
Spring, Hibernate, and Struts are examples of advanced Java frameworks.
What exactly are Servlets?
What options do they have? What is the purpose of them?
What does a Servlet look like in code?
GET, POST, PUT, DELETE, TRACE, OPTIONS are all HTTP methods.
Differences between GET and POST requests
Lifecycle of a Servlet
Servlet Context and Servlet Config are two types of servlet configuration.
Requests are forwarded and redirected.
4. Session Control
What exactly is a session?
Why is it necessary?
How can I schedule a session?
Information about the session is passed back and forth between the client and the server.
Cookies and rewriting are two techniques for transferring session information.
How to Terminate a Session
JSPs (Java Server Pages)
The importance of JSPs and an introduction to JSPs
HTML tags for beginners
Lifecycle of a JSP
Elements in JSP
The importance of the above elements and their integration into the JSP Lifecycle
In JSP, what are directives?
Include directives on the page
JSP Tag Library Directive No. 7
The principles of the JSP Standard Actions Expression Language (JSTL) and how to use it
Custom Tag Library is Required
Implementation of a Custom Tag Library
Framework for Struts (version 2.x)
1. MVC Fundamentals
What exactly is MVC?
Types 1 and 2 of MVC architecture
What is the purpose of the Struts framework?
Overview of Struts 1
Comparison of Struts 1 and Struts 2
Struts 2 Architecture is the second version of the Struts framework.
The following components are explained in the architecture diagram:
Model, Views, and Controller Interceptors in the Struts Framework
Classes for models and actions
OGNL Value Stack
Configuration overview; framework and application architecture
Approaches to configuring Declarative and Annotations
