Question

Assume that a Money variable yearlySales has also been declared. Write the necessary code that traverses the monthlySales array and adds it all up and stores the resulting total in yearlySales. Be sure make sure that yearlySales ends up with a valid value, i.e. a value of cents that is less than 100.

Answer 1

public class num3 {

public static void main(String[] args) {

double yearlySales =0;

int [] monthlySales = new int[12];

for(int i = 0; i<monthlySales.length; i++) {

yearlySales= yearlySales += monthlySales[i];

}

}

}
