Kotlin - Basics and JVM Runtime

Which of the following is the correct syntax for a Kotlin main function without parameters?

Amain fun() { println("Hello") }

Bfun main() { println("Hello") }

Cfun main(String[] args) { println("Hello") }

Dfun main(args: String) { println("Hello") }

Step-by-Step Solution

Solution:

Step 1: Recall Kotlin main function syntax
The correct syntax for main without parameters is fun main() { ... }.
Step 2: Check each option's syntax
The option 'main fun() { println("Hello") }' has incorrect keyword order. 'fun main(args: String) { println("Hello") }' uses wrong parameter type. 'fun main(String[] args) { println("Hello") }' uses invalid Java-style syntax. Only 'fun main() { println("Hello") }' matches correct Kotlin syntax.
Final Answer:
fun main() { println("Hello") } -> Option B
Quick Check:
Main syntax no params = fun main() [OK]

Quick Trick: Main function syntax: fun main() { } [OK]
