Modern Java in Action

Let's write a GitHub Crawler and let's throw in everything Java (21) has to offer:
◦ virtual threads and structured concurrency,
◦ pattern matching and data-oriented programming,
◦ type inference, records, and sealed types,
◦ text blocks and template strings,
◦ a modern HTTP client and improved collections,
◦ modules and OS-specific binaries.

The end result will look very different from just a few years ago, let alone 10. This is not your dad's Java!

20:00 I would be interested in a dedicated video to these reflection capabilities.

Great talk/presentation, showing a lot of the new features in a connected way while also giving some additional information about them and their

[javaRelated]

Thanks Nicolai, Great Talk as expected.

Good talk Nicolai, love the frequent uploads on the channel.

[cckiez]

Banger video, love coding sessions like this. Keep it up!

[nuclearscissors]

Great talk! Loved the structured concurrency bit, pattern matching (blew my mind a few times in the talk with how awesome the code looks with it), string templates and other new features overall. Java 21 has really upped it's game in terms of neat tricks that make the life easier.

KUDOS! Awesome presentation! and remarkable job from the Java team!
Please guys, bring the null check with ? and something similar to elvis operator to the lenguage!

[stefumies]

Great presentation, and what a lovley theme, what is it and which font?`Its crisp and clear

[muzzletov]

i used ktor for that exact purpose. i feel like, oracle took a lot of inspiration from kotlin.

36:04 Pretty.pageList -> what if page is null? Should we put additional check for that?

[prdoyle]

Great talk!

Editor - looking at Nicolai is cool and all, but you need to keep showing the code or we can't follow along.

Super lovely, thanks! But "abusive, " indeed :) Imagine handling a new type of GH page... How many switch-es were there?

[hba]

30:42 Beautiful String Templates that were not appreciated.

[rahulvijay]

I have 1yr of experience as a java developer..after i see this video makes me think i am a joke 🤡

[yonishachar]

22:26 - I hate when tutorials show how to do stuff and then say "super simplified", what exactly is simplified here?

[jfkwasnoscope]

The string interpolation is still super ugly and should be replaced and yes I read the explanation for this incredibly unpractical and ugly design in the jep. It's not just a "small amount of convenience" that we're missing out on.

These highly professional people have no concept of quality screencasts, do they? The wastage of time in Java community is like no other. Untangling complexities too remains elusive.

records immutable = bad
copyOf just to make immutable list = bad
we had better solutions for all of this long time ago

why intellij? eclipse is better for java
