Which Java statement prints a blank line?

The chosen statement, System.out.println(), is correct for printing a blank line in Java. This method is designed to print the string representation of the argument passed to it. When no arguments are specified, as in this case, it effectively outputs nothing and then moves the cursor to the next line. This behavior is precisely what constitutes printing a blank line.

In contrast, System.out.print("") technically prints an empty string but does not move the cursor to a new line, leaving the output on the same line. System.out.print() without any arguments will result in a compilation error because the method requires at least one argument. Lastly, System.out.newline() does not exist in Java's standard printing functions, hence it would not produce any output. Thus, the most appropriate option for generating a separate blank line is indeed System.out.println().
