Lynda - Learn Java Concepts By Example

Do you learn best by doing? Why not learn Java that way? Learn Java Concepts by Example is a Java cookbook that pairs four Java programming challenges with step-by-step solutions. Julian Robichaux shows how to create command-line applications to search text and access a relational database, a GUI app to display and resize images, and a Java API to access third-party webpage content. By practicing these examples, you'll learn concepts such as regular expressions, arrays, JDBC, JAR files, Swing, Java math, lambdas, and RESTful programming—all within the context of real-world applications.

Topics include:

Creating a command-line application

Building a graphical user interface

Creating a Java API

Parsing JSON data

Refactoring and testing Java code
