Fast Track to Core Java 8 Programming for OO Experienced Developers (TT2104-J8) Eğitimi

Who Should Attend?

This is an introductory-level Java programming course, designed for experienced developers who wish to get up and running with Java, or who need to reinforce sound Java coding practices, immediately. Attendees should have a working knowledge of developing OO software applications (coming from C++, C# or other OO programming backgrounds).

This “skills-centric” course is about 50% hands-on lab and 50% lecture, designed to train attendees in core OO coding and Java development skills, coupling the most current, effective techniques with the soundest industry practices. Our engaging instructors and mentors are highly experienced practitioners who bring years of current "on-the-job" experience into every classroom.

Working in a hands-on learning environment, guided by our expert team, attendees will learn to:

• Understand not only the fundamentals of the Java language, but also its importance, uses, strengths and weaknesses
• Understand the basics of the Java language and how it relates to OO programming and the Object Model
• Learn to use Java multi-threading and exception handling features
• Understand and use classes, inheritance and polymorphism
• Understand and use collections, generics, autoboxing, and enumerations including new Java features and capabilities
• Become familiar with the concept of functional programming using Lambda Expressions
• Process large amounts of data using the Stream API introduced in Java 8
• Take advantage of the Java tooling that is available with the programming environment being used in the class
• Specific Java 8 features: The new Date API, Lambda Expressions, Streams, Collectors
