Java 8 is an important upcoming release that changes a lot of things, from the introduction of lambdas and the Stream API to Nashorn JS engine, improved Fork-Join framework and an update of concurrency primitives.We all have seen examples of those features in presentations and tutorials, however it is interesting to feel how these changes will affect a random project migrating to Java 8.
In this article, we take a small project--in this case a zip archive processing library called zt-zip--and migrate it to Java 8. Is real-world code full of opportunities to use lambda expressions? How easy is it to rewrite your loops using the Stream API?
Armed with Intellij IDEA’s support for Java 8 and a bunch of unit tests, which turn out to be extremely helpful, we modernize our small Java 1.4-compatible project (that’s right! :-D) and note what goes well and what doesn’t.
