I'm in intro to Java can you please use only printf for all printings.

(Stopwatch) Design a class named StopWatch. The class contains:

*Private data fields startTime and endTime with getter methods.

*A no-arg constructor that initializes startTime with the current time.

*A method named start() that resets the startTime to the current tme.

*A method named stop() that sets the endTime to the current time.

*A method named getElapsedTime() that returns the elapased time for the stopwatch in milliseconds.

Write a test program that measures the execution time of sorting 100,000 numbers using selection sort.

Can you use only printf for all printings.
