Question

Given:
public class Main {
public static void main(String[] args) {
import java.time.LocalDate;

var today = LocalDate.now().with(TUESDAY).getDayOfWeek();
switch (today) {
case SATURDAY:
System.out.println("Weekend");
break;
case MONDAY:
case FRIDAY:
System.out.println("Working");
break;
default:
System.out.println("Unknown");
}
}
}
What is the result?

Explanation

Option B would be correct if the code compiled, but there's a critical issue the question is testing: import statements in Java must appear at the top of the file, before any class declaration - they cannot be placed inside a method body. This means the code actually fails to compile, making D the true correct answer and suggesting an error in the answer key.

Setting that aside and examining the intended logic: LocalDate.now().with(TUESDAY) adjusts the current date to the nearest Tuesday (using DayOfWeek as a TemporalAdjuster), and .getDayOfWeek() then returns DayOfWeek.TUESDAY - a constant, not a String. The switch statement lists cases for SATURDAY, MONDAY, and FRIDAY, but has no case TUESDAY, so execution falls through to default and prints "Unknown".

The distractors fail for these reasons: A (WorkingUnknown) requires two prints but only one path executes; C/E (Tuesday) confuse the DayOfWeek enum with its string name - getDayOfWeek() returns the enum value, which can't be printed directly in that context; F (Working) would require the day to be MONDAY or FRIDAY; and while D is actually the most defensible answer given the import-inside-method error, the question intends to ignore that.

Memory tip: In Java, import belongs at the top of the file - think of it as the "guest list at the door," not something you check mid-conversation. And whenever you use .with(DayOfWeek.X), remember you get back that exact day of week - always ask yourself whether your switch actually has a matching case for it.
