Kotlin-Kotlin Coding Guide

Example

Using safe calls (`?.`), the Elvis operator (`?:`), and non-null assertions (`!!`).

Scenario

Prevents runtime NullPointerExceptions, particularly useful in Android development where null references are common.

Example

Adding new functionalities to existing classes without modifying their source code.

Scenario

Enhancing the standard Java API to include custom utility methods, enabling cleaner code organization.

Example

Using `launch` and `async` to manage concurrency.

Scenario

Improves asynchronous programming by managing complex asynchronous tasks, particularly in network or I/O-bound operations.

Example

Defining a simple data class: `data class User(val name: String, val age: Int)`.

Scenario

Simplifies the creation of classes to store data by automatically generating methods like `equals`, `hashCode`, and `toString`.

Example

Declaring variables without specifying types: `val name = "Kotlin"`.

Scenario

Makes code more concise and readable while maintaining strong typing, beneficial when prototyping or building large applications.
