Java Programming

The course builds a strong understanding of JDBC Technology. It gives in to demonstrate why Servlets are the cornerstone of Java’s Web platform. It then shows how JSP is built on the Servlet architecture.

Additionally, the class shows students how to use JSTL, custom tags and expression language to reduce Java code in Web pages while adding tremendous power and capability to those pages. The class culminates in an exploration of Java MVC frameworks like Struts at a high level.

This is not a class that focuses on theory. Participants will find the course is loaded with practical labs and simulations. After taking this class, developers will be able to build Web applications that perform well, are scalable, and that are easier to maintain.

Advanced Java Training Course Objective:

Learn the fundamentals of JDBC and using the different interfaces in the JDBC API. Learn how to use Java servlets in the role of Web application control. Identify the options to state management in a Java Web application and understand the pros/cons of each.

Understand how JSPs can help to separate Web logic and functionality from page layout. Explore how to make JSPs smaller and more powerful with JSTL, custom tags and expression language. Explore strategies in the exchange of data between Web pages (views) and business processing (model). Learn the meaning and importance of MVC

Advantages:

• Java offers higher cross-functionality and portability as programs written in one platform can run across desktops, mobiles, and embedded systems.
• Java is free, simple, object-oriented, distributed, supports multithreading, and offers multimedia and network support.
• Java is a mature language and, therefore more stable and predictable. The Java Class Library enables cross-platform development.
• Information-packed practical training starting from basics to advanced testing techniques.
• Being highly popular at enterprise, embedded and network level, Java has a large active user community and support available.
• Course content designed by considering current software testing technology and the job market.
• Unlike C and C++, Java programs are compiled independent of platform in bytecode language which allows the same program to run on any machine that has a JVM installed.

Java has powerful development tools like Eclipse SDK and NetBeans which have debugging capability and offer integrated development environment.
