Basic Java and OO Programming Essentials for Developers New to OO (C, COBOL, 4GL, etc.) (Java 9 to 1

Basic Java 11 and OO Prorgramming Essentials for Developers New to OO is a five-day, hands-on Java training course geared for developers who have little or no prior working knowledge of object-oriented programming languages (such as those working on (C, COBOL, 4GL, etc.) Throughout the course, students learn the best practices for writing great object-oriented programs in Java 10, using sound development techniques, new improved features for better performance, and new capabilities for addressing rapid application development. Special emphasis is placed on object oriented concepts and best practices.

This course explores several items introduced in Java 9, Java 10 and Java 11 including the Java Modular System, Local Variable Type Inference, the HTTPClient API and several API updates. Developers leaving this course will be able to work on Java 8 projects while they are also ready to move onto projects using Java 11. This course also inlcudes a Quick Look at what s next in Java Java 12, Java13, Java 14 and beyond.
