You use a static method by writing the name of the class where it is
defined followed by . and the method name.
class StuffDoer {
static void doStuff() {
IO.println("Doing stuff");
}
}~class StuffDoer {
~ static void doStuff() {
~ IO.println("Doing stuff");
~ }
~}
~
void main() {
StuffDoer.doStuff();
}
