Java 9/10 Programming for Object Oriented Experienced Developers

Learn the best practices for writing object-oriented programs in Java 10, using sound development techniques, new improved features for better performance and new capabilities for addressing rapid application development.

Java 9/10 Programming for Object Oriented Experienced Developers is a five-day, comprehensive hands-on java training course geared for developers who have prior working knowledge of object-oriented programming languages such as C# or C++. 

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. 

Java 9/10 Programming for Object Oriented Experienced Developers introduces several aspects that were introduced 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 9 or 10.

**Note: Students new to OO programing or from a Non-OO Development background (such as C, COBOL, Visual Basic, etc.) should consider the  Java 10 and OO Essentials for Developers New to OO.
