Training Description

This course provides a guided, in-depth introduction to the Java programming language, highlighting key benefits and features. Students will learn about object-oriented programming concepts, Java's core packages, creating graphical user interfaces with Java, and file input and output from within Java.

Training Objectives

As a result of taking this course, you will be able to:

  • Describe and obtain an overview of Java's capabilities, benefits and features.
  • Define object oriented programming concepts and their implementation in Java.
  • Utilize classes from Java core packages in a Java application.
  • Create a graphical user interface (GUI) using Java classes.
  • Program using Java event listeners.
  • Build programs that directly read and write operating system files from within Java.

Prerequisites

Prior programming experience with any procedural or object-oriented language. Experience with SQL is helpful. Experience with graphically- oriented IDEs, such as Eclipse, is helpful.
