"Small" things I highly appreciate about Kotlin coming from Java - Chapter 3

𝐃𝐞𝐟𝐚𝐮𝐥𝐭 & 𝐍𝐚𝐦𝐞𝐝 𝐀𝐫𝐠𝐮𝐦𝐞𝐧𝐭𝐬

kotlinlang.org/docs/functions.

Cleaner, more flexible syntax. No more explosion of method/constructor overloads. No more Builders for every class or record. No more abusing Maps for passing optional parameters around.

Generated with OpenAI: The image shows a snippet of Kotlin code that defines a data class named KeepAlive. This class has four properties: connections of type UInt, requests of type UInt with a default value of 1000u, time of type Duration with a default value of 1.hours, and timeout of type Duration with a default value of 60.seconds. The code also includes an instance of the KeepAlive class named keepAlive, initialized with connections set to 64u. The code imports the necessary components from the kotlin.time package to handle durations in hours and seconds. This code is interesting because it demonstrates how to set default values for class properties.
Generated with OpenAI: The image shows a Java code snippet defining a record named KeepAlive. The code imports the java.time.Duration class and defines the KeepAlive record with four fields: int connections, int requests, Duration time, and Duration timeout. There are two constructor overloads: one that initializes all the fields, and another that only requires the connections field while setting default values for the others (1000 for requests, Duration.ofHours(1) for time, and Duration.ofSeconds(60) for timeout). Additionally, there is a validation block that throws an IllegalArgumentException if the connections or requests fields are negative.
