Java object destructuring

java object destructuring

In javascript there is object destructuring so we can break down objects and just use the end key if the intermidiate objects are resused multiple times. e.g)

const person = {
  firstName: "Bob",
  lastName: "Marley",
  city: "Space"
}

So instead of calling person.<> to get each value we can destructure it like this 

console.log(person.firstName) 
console.log(person.lastName) 
console.log(person.city)

Destructured:

const { firstName, lastName, city } = person;

And call like this:

console.log(firstName)
console.log(lastName)
console.log(city)

Is there something similar in Java? I have this Java Object that I need to get the value from and have to call long intermediate object names like this: 

myOuterObject.getIntermediateObject().getThisSuperImportantGetter()
myOuterObject.getIntermediateObject().getThisSecondImportantGetter()
...

I would like this destructure it somehow and just call the last method getThisSuperImportantGetter(), getThisSecondImportantGetter() for cleaner code.

As far as i know, java doesn't support this.

Other JVM language called Kotlin does support this
