Java Programming Essentials for Developers New to OO (TT2120J9) Course Details:

Java 9 and OO Essentials is a five-day, comprehensive 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 9, 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 introduces new features in Java 9 and Java 10, including the Java Modular System and Local Variable Type Inference. Developers leaving this course will be able to participate in projects that are still on Java 8, while they are also ready to move onto projects using Java 10.

    No classes are currenty scheduled for this course.
