In the meantime, please contact hall@coreservlets.com for information on a customized onsite version at your location. Lower price, more convenient for your developers, and customizable content. Full-day courses can be held at any location worldwide, but for clients in the Baltimore/Washington area, late afternoon, evening, or weekend sessions can also be arranged.

“Wonderful. In 20 years, this is the best organized, most pragmatic and enjoyable course I've taken.”

“The best instructor-led course I have attended, by far.”

“Best short course ever!”

“Compared to the other short courses I have taken, this one completely redefined my scale from 1-10.”

“In my 35+ years of taking technical courses, Marty's classes consistently come out ranking #1 on my list. Highly relevant material is delivered with enthusiasm, humor, and a high degree of class interaction that is unmatched anywhere.”

Course Overview

Java is the world's most popular and widely-applied programming language, but it is large, complex, and sometimes difficult to get started with. This course gives a practical, hands-on introduction to programming with Java 7 and Java 8, the latest versions of the language. The course provides thorough coverage of the the foundational Java topics: basic syntax, object-oriented programming, and core data structures; it also gives a fast-moving survey of some of the most important libraries: graphical user interfaces, multithreaded applications, network programming, serialization, and database access. It also gives an introduction to lambdas and streams in Java 8, the most important features in the upcoming new release of Java. In each section, it gives details on the most important topics, surveys more advanced or lesser-used topics, stresses best practices, and gives plenty of working examples. Each section is followed by a series of hands-on exercises that use Java and Eclipse to reinforce the concepts. There are a choice of exercises of varying complexity so as to accommodate developers with various levels of expertise and previous experience.

Marty normally runs on-site training courses at customer locations. This is easier administratively, is better for clients since the topics and schedule can be customized, and is more cost effective for students since no travel is required. However, due to demand from those who do not have enough students for an on-site course, Marty will be running a public (open enrollment) Java training course at the Johns Hopkins Dorsey Center in Elkridge MD.

The course is developed and taught by Marty Hall, an experienced developer, award-winning instructor, popular conference speaker (5 times at JavaOne), and author of several bestselling Java books.

About the Instructor

Marty Hall is the author of six popular Java EE books, including Core Servlets and JavaServer Pages, the all-time worldwide bestselling servlet/JSP book, published in Bulgarian, Chinese Simplified Script (Mainland China), Chinese Traditional Script (Taiwan), Czech, Greek, English, French, German, Hebrew, Japanese, Korean, Macedonian, Polish, Portuguese, Russian, and Spanish. Marty is president of coreservlets.com, a training and consulting company focusing on server-side Java technology and Rich Internet Apps with Ajax. In addition to long Java development and consulting experience, Marty has an extensive background in teaching and training, having given training courses on J2EE, JSF 2.0, GWT, and Ajax topics in Japan, Canada, Australia, the Philippines, Mexico, Puerto Rico, India, Cambodia, and dozens of US venues. A popular and entertaining speaker, Marty has spoken at conferences and user groups around the world, including Comdex, the Web 2.0 Expo, the Great Indian Developer Summit, and five times at JavaOne. Marty is also adjunct faculty in the Johns Hopkins University part-time graduate program in Computer Science, where he directs the Java and Web-related concentration areas.

Prerequisites

The course consists of an approximately equal mixture of lecture and hands-on lab time. The course assumes that all students are experienced programmers in some language: this is not a course for first-time programmers. Experience with C, C++, C#, or Objective-C is particularly helpful.

Please note: if you are already comfortable with Java, and just want to learn the new Java 8 features (lambdas, method references, streams, the java.util.function package, defender methods, etc.), don't take this course: take the one-day Java 8 course instead.

Venue

JHU/EP Logo The course will be held at the Johns Hopkins Dorsey Center in Elkridge, Maryland. This is a modern, comfortable venue with separate computers for each student, fast internet connections, and with coffee, snacks, and meals included. Class meets from 8:30 am to 4:30 pm daily. For students who prefer to bring their own laptops, fast wifi is available, and you can email the instructor for information on installing the class software in advance.

For Maryland residents, the location is centrally located 5 minutes from BWI airport and has plenty of free parking. For out-of-town students, there are many hotels within 1 mile.

Registration

The five-day course costs $2695 per student and includes an extensive course notebook, a commercial textbook, exercises, and exercise solutions. Free breakfast, snacks, and lunch. Compare this price to courses from Learning Tree, GlobalKnowledge, and Oracle University that cost $3500-$4200 for five-day courses and $2800-$3000 for four-day courses and that do not include textbooks or meals. Besides, those courses almost always use an unknown instructor who did not develop the course materials and often lacks significant real-world development experience.

To register, fill out and send in the course registration form. Space is limited: five previous offerings of coreservlets.com courses were full. Bonus: Register at least two weeks in advance and get a $100 gift certificate from amazon.com.

Syllabus

Course now includes an introduction to lambdas in Java 8 (with exercises!). However, if you are already comfortable with Java, and just want to learn the new Java 8 features (lambdas, method references, streams, the java.util.function package, defender methods, etc.), don't take this course: take the one-day Java 8 course instead.
