Problem Statement
What is an object declaration in Kotlin?
Explanation
Object declarations use the object keyword to create singletons lazily initialized when first accessed, ensuring only one instance exists throughout the application. You can access members directly through the object name without calling constructors, and objects can implement interfaces and extend classes like regular classes.
Object declarations are thread-safe by default with initialization guaranteed to happen only once even in concurrent access scenarios. They're perfect for implementing singletons, creating companion objects, or defining anonymous objects for one-off implementations without the boilerplate of singleton patterns in Java.
