About This Course
This is a 2-day course on Java programming where you will be introduced to the basics of Java programming: data types, strings, arrays, expressions, loops, and functions. You’ll learn how to control the flow and logic of your code and create classes using the principles of object-oriented design. Then go a bit beyond the basics and learn advanced techniques for working with arrays, manipulating files, and building graphical user interfaces (GUIs) that respond to user input. This course is perfect for developers who need to get up to speed with Java fast, as well as for beginning programmers who want their first taste of this popular language.
Learning Objectives
- Understand Java basics – data types, strings, arrays and more.

- Understand how to use reflection API and navigate inheritance trees.
- Learn how to use managing unordered and ordered sets, peeking and polling with queues.
- Understand the testing and error handling skills, managing files and directories,working with I/O streams and multi-threading.
