Introduction to Java 9/10 Programming for Developers New to OO Programming

Java 9/10 and OO Programming 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.  

Java 9/10 and OO Programming Essentials for Developers New to OO 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 10

Note: Students with prior Object-Oriented exposure and background (such as C#, C++, Smalltalk, etc.) should consider the TT2100-J9-10 Java 9/10 Programming for Object-Oriented (OO) Experienced Developers as an alternative.
