Listing the Elements of a Collection(iterate over the elements of set or list)

      

import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;

public class Main {
  public static void main(String[] argv) throws Exception {
    Set collection = new HashSet();

    // For a set or list
    for (Iterator it = collection.iterator(); it.hasNext();) {
      Object element = it.next();
    }
  }
}
