Swift and Java control flow comparison

1. The for-in loop in Swift is very similar to foreach in Java, simplifying the traversal of the collection.

Swift syntax:

   forIndexinch 1...5{print ("The index is \ (index)")} LetBase=3Let power=3var answer=1         for_inch 1... power {Answer*=Base} print ("\ (base) to the power of \ (power) is \ (answer)")        //output "3 to the power of 59049"

The Java syntax is as follows:

      New Arraylist<string>();        Array.add ("a");        Array.add ("B");        Array.add ("C");        Array.add ("D");          for (String item:array) {            System.out.println (item);        }
