Java 8 Programming for OO Experienced Developers (TT2100-J8)

GK# 1510 Vendor# TT2100-J8

Course Overview

TOP

This course is geared for developers who have prior working knowledge of object-oriented programming languages such as C++. You will learn the best practices for writing great object-oriented programs in Java 8, using sound development techniques, new improved features for better performance, and new capabilities for addressing rapid application development. In addition to the normal exercises that are liberally sprinkled throughout the course, there is a case study that covers the entire spectrum from use cases to object-oriented design to implemented classes. This case study supplements the course and can be used during and after the course as a reference and a tool for reviewing and practicing what was learned in class.
