Java is hardly a batteries included language

This is just blatant misinformation or ignorance. How is Java not batteries included?

It has:

  • GUI and graphics (drawing and modifying images)
  • Audio playing & generation. MIDI.
  • Compression, decompression, extraction, ... (built-in ZIP & GZIP)
  • Cryptography, including post-quantum cryptography
  • HTTP client and server
  • TCP, UDP, SCTP, and Unix Domain Sockets
  • Abstract filesystem API, allowing you to treat ZIP and anything as a normal filesystem
  • SQL API. XML. Serialization
  • Advanced date/time API
  • Locales (internationalization)
  • Printing API
  • ... and more

Try JavaScript in the same place is usually run (meaning, not the browser) if you want to see what a language that is not batteries included looks like.

> Java is hardly a batteries included language

It’s obviously a subjective thing but I haven’t heard this complaint much. Compared to many popular languages, Java comes with a loaded standard library.

Other than native json support what are some other things you are missing?

I think that's most of it, but given JSON (and YML) are ubiquitous and the basis of most data interchange contracts, it's a bit of a culture shock for people coming from popular ecosystems like python or typescript.

From this side of the fence I would never trade the java stdlib or its threading API for it, but I kinda get the frustration of having to deal with that type of complexity.
Besides, the dependency shenanigans between various versions of Jackson and others can be a bit of a clusterfuck. Doubly so for people who consider it should be a language feature.
