Using the For-Each Loop with Collections
<![CDATA[
For-Each Loop can be used to any object that implements the Iterable interface.
This includes all collections defined by the Collections Framework,
import java.util.ArrayList;
public class MainClass {
public static void main(String args[]) {
ArrayList<Double> list = new ArrayList<Double>();
list.add(10.14);
list.add(20.22);
list.add(30.78);
list.add(40.46);
double sum = 0.0;
for(double itr : list)
sum = sum + itr;
System.out.println(sum);
}
}
