Hi Friend,

Try it:

import java.util.ArrayList;

public class ThreeArrayLists{
public static void main(String[] args) {
ArrayList priceList = new ArrayList();
ArrayList quantityList = new ArrayList();
ArrayList amountList = new ArrayList();

priceList.add(new Double(10.62));
priceList.add(new Double(14.89));
priceList.add(new Double(13.21));
priceList.add(new Double(16.55));
priceList.add(new Double(18.62));
priceList.add(new Double(9.47));
priceList.add(new Double(6.58));
priceList.add(new Double(18.32));
priceList.add(new Double(12.15));
priceList.add(new Double(3.98));

quantityList.add(new Double(4.0));
quantityList.add(new Double(8.5));
quantityList.add(new Double(6.0));
quantityList.add(new Double(7.35));
quantityList.add(new Double(9.0));
quantityList.add(new Double(15.3));
quantityList.add(new Double(3));
quantityList.add(new Double(5.4));
quantityList.add(new Double(2.9));
quantityList.add(new Double(4.8));

for(int i = 0; i < 10; i++){
amountList.add((Double.valueOf(priceList.get(i).toString())) * (Double.valueOf(quantityList.get(i).toString())));
System.out.printf("%d)%.2f*%.2f = %.2f\n", i + 1, Double.valueOf(priceList.get(i).toString()),
Double.valueOf(quantityList.get(i).toString()), Double.valueOf(amountList.get(i).toString()));
}
}
}

Anyways, if you got error again then send the error also.

Thanks
