Rahul Singh presented on Java. Java is a general-purpose, object-oriented programming language that is designed to have as few implementation dependencies as possible so that code can run on any Java virtual machine. Key principles of Java include that it must be simple, robust, architecture-neutral, portable, high-performance, and interpreted/threaded/dynamic. Java has been updated through various versions since its initial release in 1995 and the Java platform allows programs to run similarly on different hardware/operating systems using Java bytecode. Rahul Singh promotes Java training provided by Iteducenter.
Introduction to Spring Framework and Spring IoCFunnelll

This document provides an overview of Jakarta EE 8 and the future plans for Jakarta EE 9 and beyond. It discusses how Java EE was donated to the Eclipse Foundation and renamed to Jakarta EE. It outlines the release timeline and key features of Jakarta EE 8. It also summarizes the goals and proposed changes for Jakarta EE 9, including renaming javax packages to jakarta and tooling updates. Finally, it speculates on potential new specifications that could be added to Jakarta EE in the future.
Frameworks are large prewritten code to which you add your own code to solve a problem in a specific domain.
You make use of a framework by calling its methods,inheritance,and supplying “call-backs” listeners.
Spring is the most popular application development framework for enterprise Java?.
Millions of developers use Spring to create high performing, easily testable, reusable code without any lock-in.
Spring AOP allows for aspect-oriented programming in Spring applications. It provides a way to separate cross-cutting concerns like logging, security and caching into reusable modules called aspects. Aspects define advices that specify actions to be taken at certain join points during execution of methods. The main AOP concepts are aspects, advices, join points, pointcuts and weaving. Advices like before, after, around etc allow code to run before, after or around method executions. Pointcuts define which method executions match, allowing advices to be selectively applied based on method signatures or argument types. Weaving is the process of integrating aspects into classes at compile-time, load-time or runtime.

This document provides an overview of the Java programming language and environment. It discusses what Java is, its uses as both a programming language and platform, and the key components of the Java platform including the JRE and JDK. It also covers downloading and installing the JDK, configuring the environment, and creating a simple "Hello World" Java program. The document includes many screenshots to illustrate the various steps and configurations.
Previously we had begin with Java Tutorial beginners guide featuring – What is Java , features of Java Programming Language , Java editors and different Java editions and Java Application Types . Now on Java tutorial we begin with the section 2 that is about JVM – Java Virtual Machine . And also about the difference between JDK Vs JRE Vs JVM including other aspects of Java Virtual Machine .

This document provides an overview of Apache Tomcat, a free and open-source web server and servlet container developed by the Apache Software Foundation (ASF) that implements the Java Servlet and JavaServer Pages (JSP) technologies. It discusses what Tomcat is, its role as a web application container, how to install and configure it, enable features like CGI and SSI, and addresses some common issues. The advantages of using Tomcat include that it is open source, lightweight, easily configured, stable, well documented, and free.
The JDK contains the JRE plus development tools like the javac compiler and java runtime. The JRE contains libraries and files used by the JVM at runtime. The JVM provides the runtime environment to execute bytecode and allows Java to be platform independent, though the JVM itself is operating system dependent.
