Looping Through a Collection
To loop through a collection, use the hasNext() and next() methods of the Iterator:
import java.util.ArrayList;
import java.util.Iterator;
public class Main {
public static void main(String[] args) {
// Make a collection
ArrayList<String> cars = new ArrayList<String>();
cars.add("Volvo");
cars.add("BMW");
cars.add("Ford");
cars.add("Mazda");
// Get the iterator
Iterator<String> it = cars.iterator();
// Loop through a collection
while(it.hasNext()) {
System.out.println(it.next());
}
}
}
