Your program analyzes complex data. You are going to read text from a file as part of your program.
The program is saved in a folder, which has a subfolder called "numbers."
In the info folder is a text file called "sales. txt."
Which line of code will open sales. txt?

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system.currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.
