Java 8 Programming and Object Oriented Essentials for Developers New to OO (TT2120-J8)

GK# 0391 Vendor# TT2120-J8

Course Overview

TOP

This course is geared for developers who have little or no prior working knowledge of object-oriented (OO) programming languages (such as C, COBOL, 4GL, and so forth). Throughout the course, you will learn the best practices for writing great OO programs in Java 8, using sound development techniques, improved features for better performance, and new capabilities for addressing rapid application development. Special emphasis is placed on OO concepts and best practices.
