Modern Java in Action

Let's write a GitHub Crawler and let's throw in everything Java (21) has to offer

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!
