Part 1: Select ten foreign currencies and find the current exchange rate. Since currency exchange rates change often, you will need to look up the exchange rates. You can call a bank or look for foreign currency exchange rates on the Internet or in a newspaper. Part 2: Create a spreadsheet that lists the ten currencies you chose. For each currency, enter an amount and create a formula to convert it to U. S. dollars. Make sure to include dollar signs on appropriate cells.

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.
