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!
