The ‘static import’ allows you to refer to things like this:
import static java.util.Collections.sort;
public class ScratchTest {
public static void main(String[] args) {
java.util.List list = sort(java.util.Collections.singletonList(new
Object());
}
}
but typically, the static import is used for constants, although for some types
of routines it is used to make the code read like a DSL.
