Discover how to use the CompletableFuture class in Java.

At hackajob HQ, one of our favourite features in Java 8 is the Optional Feature. Helping to avoid unexpected errors and write clean code, in today’s article, we’ll be covering it in detail.

In our previous Java 8 article, we spoke about the benefits of the Collection API. In today’s write-up, we’ll be taking a closer look at Collectors and how to use them in Java 8.

In part one of this article, we covered the ‘forEach’ method, the ‘Collection.removeIf’ method, the ‘Iterator.forEachRemaining’ method and the ‘SplitIterator’ interface. For part two, we’ll be looking at the improvements made on both the ‘List’ and ‘Map’ interfaces.

Java 8 has made some significant improvements to the Collection API and in part 1 of this article, we’ve decided to jump right in.

Following on from our previous tutorial, today we’re going full steam ahead with part 2, this time focusing on ‘ZonedDateTime’.

One of the latest features to be introduced in Java 8 is the ‘DateTime API’. Enabling users to easily perform date and time manipulation, this new feature is one of Java 8’s most exciting to date (it’s certainly loved by the hackajob team!).

A new concept introduced in Java 8, functional interfaces were added to support lambda expressions. We’ll be covering what functional interfaces are and the reason why they were added to Java 8, as well as the benefits they provide.

Java 8 has introduced a new feature called the ‘Method Reference Operator’. In this article, we’ll be explaining what method references are, as well as the different types of method references available.
