Java Fundamentals: The Core Platform
Beginner • 7h 25m
Description
Java is the most in-demand programming language skill amongst software developers, and one of the most important skills for big data specialists. This course, Java Fundamentals: The Core Platform, provides thorough coverage of the core Java platform, giving you the foundation you need to begin developing Java applications using the features and capabilities of the Java Runtime Environment (JRE), as well as providing you with the skills you need to quickly ramp-up and begin developing effectively with Java using the JRE. First, you'll learn about working with streams, files, and the file system. You'll also learn about I/O topics specific to working with files such open/closing files, detecting end-of-file, and buffering. Next, you'll learn about configuring application execution and environments, the features available, and detailed discussions of the PATH and CLASSPATH environment variables that affect the Java runtime. Finally, you'll learn about multithreading and concurrency, taking a look at the basic ideas of the thread startup lifecycle along with the more sophisticated executor service. After watching this course, you'll be ready to begin working within any of the many environments that rely on Java.

Java Fundamentals: Generics
Intermediate • 3h 53m
Description
Java’s powerful generics has been available to developers for ten years now and is extensively used throughout both core and third party libraries. Unfortunately, it's not as well understood as it could be. This course is here to help. We’ll both shine a light on the common use cases of generics on classes, methods, or interfaces and also peer into some of the darker corners such as type bounds and wildcards.

Applying Concurrency and Multi-threading to Common Java Patterns
Intermediate • 2h 39m
Description
Every developer needs to know how to write multi-threaded applications in Java. This course, Applying Concurrency and Multi-threading to Common Java Patterns, is a precise presentation of all the fundamentals you'll need. You'll learn about the main problems of concurrent programming on multicore CPU, including race condition, synchronization, reentrant lock, and deadlock. Next, you'll cover how your application use is moved from the main memory to the CPU caches and how false sharing can occur. Finally, you'll be introduced to the Java Memory Model and the notion of happen-before. By the end of this course, you will understand how concurrency and multi-threading work on a variety of Java patterns and you'll be able to use this knowledge to create better apps.

Many Java web frameworks, such as Struts, are built on top of the Servlet and JavaServer Page specifications and base libraries. To fully understand how these frameworks operate, and to be able to take full advantage of the facilities they offer, you should understand the foundations such frameworks are built on. This course takes you through building a web application using the base Servlet and JavaServer Page libraries. The course discusses the Model-View-Controller pattern using Servlets as the Controller and JavaServer Pages as the View. You will also learn how to hide complex UI interaction inside tag libraries. The course will show you how it is possible to build a web application using these fundamental technologies, and how other frameworks are built.
