In this program, we use a if statement and System.out.printf() because it returns object of PrintStream which is not null when something is passed to the printf().
public class Main {
public static void main(String[] args) {
if (System.out.printf("Hello World 👋") != null) {}
}
}
whereas, System.out.println() and System.out.print() return void which cannot be used for a comparison.

Why?
can you elaborate on the question plz?
Sure. Why, as in, why would you want to deliberately use code smells, such as an empty block, etc, just to avoid a semicolon?
It's nothing but a quiz question which was asked in my university, and I thought it would be nice for the community to know it, out there. 😁
Wow, that's an unexpected (and unfair) question for a programming instructor to ask on a quiz, a question that can only be answered by using code smells.
