Java Functional Programming with Lambdas & Streams  Course

Functional programming is a way of developing software, using side-effect-free functions as basic building blocks. Functional code has some advantages: it can be more concise, more predictable, and easier to test than imperative or object-oriented code. Lambdas, which are anonymous functions, are an integral part of functional programming and were introduced in Java 8. This workshop will help Java programmers understand the new terminology and core concepts of functional programming, in particular lambdas and streams. It will teach you how to write even better Java code.

Duration: 2 days. Courses are presented from 08:30 to 16:30.
Investment: R3,900.00 excluding VAT per delegate. Prices valid from 1 February 2018.
Venue: The Incus Data Training Venue in Centurion, Pretoria. Courses can also be presented on-site for 5 or more delegates.
Dates: Please check the course schedule for the next available date. You can also contact us at tel: (+27) 12 666 2020 or email us at info@incusdata.com to find out about dates.

Audience: Is This The Right Course For Me?

You should attend the Java Functional Programming course if:

  • You are a Java programmer and you want to learn about the functional programming in Java.
  • You are a Java programmer and you need to write or maintain Java code that uses lambdas.
  • You are a Java programmer and you need to write or maintain Java code that uses the Stream API.

Prerequisites: Am I Ready For The Course?

Before you attend the Java Functional Programming course:

  • You must have attended our Java Programming course or already be comfortable with the fundamentals of the Java programming language.
  • You should have at least 6 months practical experience programming in Java.

Please ensure you meet the prerequisites for the Java Functional Programming with Lambdas & Streams Course before you attend the course. Read the importance of course prerequisites to understand why this is necessary.
