Java 8 Programming and Object Oriented Essentials for Developers New to OO Course Details:

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.

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.
