What is your favourite Java specific feature that you miss in other languages?

• Javaslang

  vʌvr (formerly called Javaslang) is a non-commercial, non-profit object-functional library that runs with Java 8+. It aims to reduce the lines of code and increase code quality.

  

I'm aware not everyone likes it, but vavr has these.

• Poetry

  377 29,483 9.7 Python

  Python packaging and dependency management made easy

  

Poetry is like NPM for Python projects.

• easy-tuples

  1 1 0.0 Java

  Easy and convenient structural tuples for Java

  

I made this library: https://github.com/easytuples/easy-tuples which tries to emulate "structural tuples". Obviously it should not be the default but sometimes it is easier to go for a structural "pair" like you say rather than naming something (naming is hard!)

• proposal-record-tuple

  ECMAScript proposal for the Record and Tuple value types. | Stage 2: it will change!

  

Well, Python has tuples and several concise ways to create records, so it must be a "feature hoarder", and it is also getting more popular than Java. You might also want to take a look at this JavaScript proposal: https://github.com/tc39/proposal-record-tuple
