4. 7. 4. Using the For-Each Loop with Collections: ArrayList

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);

  

  } 

}
