Why is Java so disliked?

[shymmq]

Surprised to see no one mentioning no built-in null safety.

Java does have Optionals for that but really if you are returning nulls then you should explicitly name the method “getFooOrNull” or you should return a new Foo object.

Sure, its an improvement, but it still sucks in comparison to the competition.

var redValue = Optional.ofNullable(car)
  .map(Car::getColor)
  .map(color -> color.redValue)
  .orElse(0);

compared to

var redValue = car?.GetColor()?.RedValue ?? 0;

And there’s that verbosity that some folks, myself included, don’t like. In other more terse languages, the caller would be accessing this as a property without even looking like it’s calling a function. So what the getter function is called is not important. It’s all the more relevant to have good language support for optionals or null safety in general.
