Make a class have function with 3 parameter (int,string,double ) with return value int in Kotlin

Question

fun main() {
    val thr = THR()
    thr.kotlin()
    thr.hitungthr(5000000, "1", 1.5)
}

class THR {
    fun kotlin() {
        println("Perhitungan THR")
    }

    fun hitungthr (gajipokok: Int, masakerja: String, jumlahthr: Double): Int {
        var MasaKerja = masakerja.toInt()
        var JumlahTHR = jumlahthr.toInt()
        var hasil = gajipokok * MasaKerja * JumlahTHR
        return hasil
    }
}

when the program is run, only the display "Perhitungan THR" appears. The second function does not appear when the program is run.

Answer 1

You need to print the value returned by the function hitungthr

fun main() {
    val thr = THR()
    thr.kotlin()
    print(thr.hitungthr(5000000, "1", 1.5))
}

Try to add print() in your main() function and try it.
