Course Description

Overview

Write Robust Java Applications with Sound Development Techniques, Improved Performance & Capabilities for Rapid AppDev.

Introduction to Core Java Programming for Object Oriented (OO) Experienced Developers is a five-day, comprehensive hands-on introduction to Java training course geared for developers who have prior working knowledge of object-oriented programming languages such as C# or C++. Throughout the course, students learn the best practices for writing great object-oriented programs in Java, using sound development techniques, new improved features for better performance and new capabilities for addressing rapid application development.

This “skills-centric” course is about 50% hands-on lab and 50% lecture, designed to train attendees in core OO coding and Java development skills, coupling the most current, effective techniques with the soundest industry practices.
 

Objectives

After completing this course, students will be able to:
  • Understand not only the fundamentals of the Java language, but also its importance, uses, strengths and weaknesses
  • Understand the basics of the Java language and how it relates to OO programming and the Object Model
  • Learn to use Java multi-threading and exception handling features
  • Understand and use classes, inheritance and polymorphism
  • Understand and use collections, generics, autoboxing, and enumerations including new Java features and capabilities
  • Become familiar with the concept of functional programming using Lambda Expressions
  • Process large amounts of data using the Stream API introduced in Java 8
  • Take advantage of the Java tooling that is available with the programming environment being used in the class Specific Java 8 features: The new Date API, Lambda Expressions, Streams, Collectors

Audience

This is an introductory-level Java programming course, designed for experienced developers who wish to get up and running with Java, or who need to reinforce sound Java coding practices, immediately. Attendees should have a working knowledge of developing OO software applications.
