Can you explain the concept of an object in Kotlin?

In Kotlin, an object is a way to create a singleton, that is, a class with a single instance. Objects are declared using the object keyword and are initialized immediately. They can contain properties, methods, and implement interfaces.

Example:

object Database {
    val name = "MyDB"
    fun connect() {
        println("Connecting to database $name")
    }
}

fun main() {
    Database.connect() // calling the object's method
}

Objects are useful when you need a single shared instance, for example, for storing settings or utilities.
