Wouldn't you need to import the class itself using a regular (non static) import first (import x.y.* or import x.y.SM), before you can import static SM's static members?

No, there is no such requirement. You can import just the static members without importing the class.

For some reason I was left with impression it was necessary. Thank you for clarifying.

But remember that if you don't import the class, you cannot access the class without package name. For example, if you have only - import static java.util.Calendar.*;

System.out.println(ALL_STYLES); //This will work fine because static members of Calendar have been made known to the compiler.
System.out.println(Calendar.ALL_STYLES); //This will NOT compile because the name Calendar is still unknown to the compiler.

What if there were two foo methods in SM.java? For instance, a public static void foo(int I) in addition to the no arg one. Which method is imported?

What happened when you tried it out?

yo, all imports, packages, and some other stuff i see egyptians hyeroglyphes... you should test your self

what i'm trying to say is that during test i have seen this:
option 2: import static x.y.SI;
option 3: import static x.y.SM.;
option 4: import static x.y.SM.foo;

now after i finished test i see this:
option 2: import static x.y.SM;
option 3: import static x.y.SM.foo;
option 4: import static x.y.SM.foo();

so ofc i selected option 4 lol it hasnt show me any () during test

shows the same in test.
