The joke is Java is verbose. It takes many characters to accomplish simple routines. Depending on your view that could either be good or bad for reading the code later.
Well I guess the point is that you shouldn’t need all these method calls to achieve simple goals. Most of those “getF” are calls to some SystemFactory to get a GenericObjectFactory and so on and so forth.
This just tells me you don’t use Java. Factory classes are just used to create objects in a standardized way, but this code isn’t creating anything, it’s just getting nested fields from already instantiated objects.
Thos code is obviously nonsense to show the issue.
But other languages would simplify stuff. For example, some languages call getters implicitly, so .getField() becomes .field. Same with list indexing, which could be done with operator overloading, so x.get(i) becomes x[i].
In this situation that would be able to reduce the character count a fair bit.
It’s not valid Java for e.g. Lists, Maps, Strings or any programmer-defined classes.
Same with operator overloading.
myVectorA + myVectorB is not valid Java, but it is valid OOP in e.g. Python or C++. And this kind of syntactic sugar reduces verbosity enourmously, while still being OOP.
If you have ever worked in e.g. Python, Groovie or Kotlin you notice quickly how non-verbose OOP can be.
It seriously is just Java.
And Javas insistance on having you wrap non-OOP things in fake OOP constructs (e.g. static methods, which are just functions in modules, but you have to uselessly abuse classes as modules) isn’t helping either.

Sure, but most of the lines in the screenshot break down to:
object1.setA(object2.getX().getY().getZ().getI().getJ().getK().getE().getF(i).getG().toString())Aside from creating a method inside the class (which you should probably do here in Java too) how would another language do this in a cleaner way?

The new convention in modern Java is to use .field() instead of .getField().
What you’re complaining about isn’t Java, it’s object oriented programming, which Java basically forces on you. Verbosity is a flaw of OOP.
Compare:
x.field[5]with
x.getField().get(5)Both are exactly the same level of OOP, but the Java version is roughly twice as long. Add operator overloading to the mix and it becomes much worse:
x.getField().get(5).multiply(6).add(3)vs
x.field[5] * 6 + 3All this has nothing to do with OOP, but with syntactic sugar that is applied.
As I said, the convention is now x.field() not x.getField()
What language are you comparing against here? x.field[5] is valid Java if field is a public array, but that’s not OOP, at least not in a pure sense.
