Answer 1

remove spaces before ()
jarak.setMil(10);
jarak.getmil()
jarak.getkilmet()
jarak.getDist()

change declaration
int km;

change method

int getDist() {
km = kilmet*mile;
return km;
}

Answer 2

Thanks for your help!
But I'm still curious, so why is it producing different value?
I don't understand 🤔
Care to elaborate?

Answer 3

Incorrect initialization of "km".
"mile" at this moment has no value

Answer 4

Oh i see, so the x haven't been assigned to the mile when the program jump to "private:" to initialize mile kilmet and km. Ok i got it. Thanks again.
