Description

Java has been significantly changed in version 8. Many long-planned features were introduced in the language, making it more functional. Using these features requires new approaches to programming and a deep understanding of new principles.

This training is designed to help participants understand the new features of Java 8. The course covers lambda expressions, data streams, stream data processing with map-filter-reduce approach, asynchronous programming and DateTime API. Every key area has a number of practical exercises that allows participants to practice what they learned.

After completing the course, a certificate
is issued on the Luxoft Training form

Objectives

To introduce developers to the features in Java 8.

Target Audience

The training is designed for Java developers.

Java and Web Technologies Expert
Catalin is an experienced and dedicated software engineer with expertise in a variety of areas such as requirements analysis, project management (Waterfall and Agile), people management, Java technologies, database design, software architecture and software technologies for Enterprise Applications. Between 2003 and 2015 he has held several roles in telecommunications and financial projects, from Java senior developer to Java technical team lead and architect.

In addition to his role as a software engineer, Catalin has also been involved in developing and facilitating trainings on programming and databases for companies and universities. He has delivered courses on subjects such as Java, Web technologies, analysis of algorithms, SQL and database design.

Since 2012, he has conducted more than 4000 hours of courses in the Luxoft Training Center. He is the author or a coauthor of the following courses:

Catalin was also the lead facilitator for the Corporate Junior Program (CJP) which took part in Luxoft Poland (Krakow and Wroclaw). This program has prepared about 50 new Java developers to join delivery projects inside the company.

Together with Luxoft, he initiated and introduced the “Advanced Java Programming” course for the students pursuing their master’s degree at the Faculty of Automation and Computer Science in Bucharest.

He is an Agile Certified Scrum Master with a deep understanding of project management techniques and plenty of experience in managing software development projects.

Code Refactoring for Java

The course deals with the concept of refactoring as a way of preventing software rot. The course describes various smells indicating that a code needs refactoring, explains which refactoring types best suit specific situations, and describes the work of refactoring in detail through analyzing concrete real-life cases.
