$\texttt{public class CUI\_Timer \{ }$

   $\texttt{// Stops the current Thread for the value passed.}$

   $\texttt{static void tick(long seconds) \{}$

       $\texttt{try \{}$

           $\texttt{Thread.sleep(seconds * 1000);}$

       $\texttt{\} catch (InterruptedException ignored) \{ \}}$

   $\texttt{\}}$

   $\texttt{public static void main(String\[[]\] args) \{}$

       $\texttt{// 2 minutes or 120 seconds}$

       $\texttt{final int TIME\_LIMIT = 2 * 60;}$

       $\texttt{for (int i = TIME\_LIMIT; i > -1; i--) \{}$

           $\texttt{int minutes = i / 60,}$

               $\texttt{seconds = i \% 60;}$

           $\texttt{System.out.printf("Time Left - \%d:\%02d \symbol{92}r", minutes, seconds);}$

           $\texttt{tick(1);}$

       $\texttt{\}}$  

       $\texttt{System.out.println("\symbol{92}nTimes Up!!!");}$

   $\texttt{\}}$  

$\texttt{\}}$

$\begin{description} \item \textendash \:\: First setting the timer limit as 2 minutes or 120 seconds. \item \textendash \:\: Iterating from \textit{TIME\_LIMIT} (120) until 0. \item \textendash \:\: Printing the time left in the timer and using the '\textbackslash r' (return carriage) \\ to clear the line. \item \textendash \:\: Stopping for 1000 milliseconds or 1 second before each iteration ends. \item \textendash \:\: Hence, creating a timer.\end{description}$
