Static functions

Static functions are functions that can be invoked without creating multiple instances of a class. Static functions avoid code duplication and can be reused.

Let's take a look at how to write a static function in Kotlin.

Consider the following code for 15a_StaticMethods.kts:

object MyUtil { fun foo(){        println("Static function foo() is invoked")    }}MyUtil.foo()

Note that we declared an object MyUtil and defined a function foo(). This is known as object declaration.

We invoked the function foo() directly using the object MyUtil.
