Use the for-each for loop to cycle through a collection.

import java.util.ArrayList;

class ForEachDemo {
  public static void main(String args[]) {
    ArrayList<Integer> vals = new ArrayList<Integer>();


    System.out.print("Original contents of vals: ");
    for (int v : vals)
      System.out.print(v + " ");

    int sum = 0;
    for (int v : vals)
      sum += v;

    System.out.println("Sum of values: " + sum);
