Receivers

The concept of a receiver, as it exists in Kotlin, does not have a direct equivalent in Java. In Kotlin, a receiver is an object that provides a specific context within a function or lambda, allowing us to interact with its properties and methods directly, without needing to explicitly reference it (e.g., using this).

It is important to note, however, that you can only interact with the properties and methods that are available at the correct access level. While the syntax may look as if the function is defined inside the class, a receiver (such as in extension functions) is essentially just syntax sugar and does not grant access to private members.

In Java, this concept is not directly available. While you can achieve similar behavior using methods or passing objects explicitly, Java lacks the syntactic sugar provided by Kotlin’s receivers. For example, in Kotlin, we can define extension functions or use lambdas with receivers, where the receiver becomes...
