How to take an array of integer as variable and print out the first element of the array in kotlin?-CodePudding

I am new to kotlin

From what I understanding this code should be working but it isn't

fun main(args: Array<Int>) {
   //printing out the first element of the array
    println(args[0])
}

main([12,3,4,5])

CodePudding user response：

The main function is the program entry point and needs to have a specific function signature.

Also, to create an array in Kotlin from hard-coded elements you would use arrayOf(). You can find more about it here.

A working example would be:

fun main()
{
    test(arrayOf(12,3,4,5))
}

fun test(args: Array<Int>) {
    //printing out the first element of the array
    println(args[0])
}
