该例子展示了一个Java集合中迭代器的常用用法
public class LinkedListTest {
public static void main(String[] args) {
List<String> a = new LinkedList<String>();
a.add("Amy");
a.add("Carl");
a.add("Erica");
List<String> b = new LinkedList<String>();
b.add("Bob");
b.add("Doug");
b.add("Frances");
b.add("Gloria");
ListIterator<String> aIter = a.listIterator();
Iterator<String> bIter = b.iterator();
while (bIter.hasNext()) {
if (aIter.hasNext()) aIter.next();
aIter.add(bIter.next());
}
System.out.println(a);
bIter = b.iterator();
while (bIter.hasNext()) {
bIter.next();
if (bIter.hasNext()) {
bIter.next();
bIter.remove();
}
}
System.out.println(b);
a.removeAll(b);
System.out.println(a);
}
}
