What does System.out.println() do?

• A. It reads input from the keyboard.
• B. It displays output on the screen and moves the cursor to the next line.
• C. It prints output without moving the cursor.
• D. It creates a new system thread.

Answer: (B)

Printing to the console in Java is done with System.out.println. It displays output on the screen and moves the cursor to the next line. System.out is the standard output stream, and println prints the given value (converting it to text if needed) followed by a line separator, which is why the cursor ends up on the next line. If you want to print without advancing to a new line, use System.out.print; println with no arguments simply prints a newline. It doesn’t read input or create new threads.
