What does the program print?

JAVA

public class Main {
    public static void main(String[] args) {
        int x = 5;
        if (x > 10)
            System.out.print("A");
            System.out.print("B");
    }
}

Expecting nothing: indentation does not group statements in Java; without braces only print("A") belongs to the if, and print("B") always runs.
Expecting a compile error: braces are optional for a one-statement branch, so the code compiles and only the indentation misleads.

How would you change the code so that neither letter is printed?
Why do style guides require braces even around a one-line branch?
