(mis)using modern Java

Tags:

Modern Java is really awesome when it comes to “Hello, World!” demos. It’s also cool for a sophisticated systems and algorithms, provided their authors write code which obeys a few fairly simple contracts and avoids obvious traps.

There are a few mantras regarding recent features of modern Java, such as:

  • records can replace JavaBeans everywhere
  • you never need to write hashCode() for records
  • pattern matching with instanceof is the best tool for equals()
  • just ignore --illegal-access and set it to permit
  • synchronize (new Long(42)) is the best for monitoring and so on.
