Create class savingsaccount. use static variable annualinter-estrate to store the annual interest rate for all account holders. each object of the class contains a private instance variable savingsbalance indicating the amount the saver currently has on deposit. provide method calculatemonthlyinterest to calculate the monthly interest by multiplying the savingsbalance by annualinterestrate divided by 12- this interest should be added to savingsbalance. provide a static method modifyinterestrate that sets the annualinterestrate to a new value. write a program to test class savingsaccount. instantiate two savingsaccount objects, saver1 and saver2, with balances of $2000.00 and $3000.00, respectively. set annualinterestrate to 3%, then calculate the monthly interest for each of 12 months and show the new balances for both savers. next, set the annualinterestrate to 8%, calculate the next month's interest and show the new balances for both savers.

Who is better at multi-tasking? in business, employees are often asked to perform a complex task when their atten-tion is divided (i.e., multi-tasking). human factors (may 2014) published a study designed to determine whether video game players are better than non–video game play-ers at multi-tasking. each in a sample of 60 college stu-dents was classified as a video game player or a non-player. participants entered a street crossing simulator and were asked to cross a busy street at an unsigned intersec-tion. the simulator was designed to have cars traveling at various high rates of speed in both directions. during the crossing, the students also performed a memory task as a distraction. two variables were measured for each student: (1) a street crossing performance score (measured out of 100 points) and (2) a memory task score (measured out of 20 points). the researchers found no differences in either the street crossing performance or memory task score of video game players and non-gamers. “these results,” say the researchers, “suggest that action video game players [and non-gamers] are equally susceptible to the costs of dividing attention in a complex task”
