如果您有以下内容

private static final class LinkedListExtension extends LinkedList<String> {
    {
        add("a");
        add("b");
        add("c");
    }
}

如何迭代LinkedListExtension的内容？

Answer 1

与普通列表相同：

LinkedListExtension myList = new LinkedListExtension();
for (String s : myList)
{
    System.out.println(s);
}

Answer 2

LinkedListExtension  list = new LinkedListExtension();
for (String s : list) { }

Answer 3

LinkedList<String> list = new LinkedListExtension();
for (String str : list)
{

}

Answer 4

使用Iterator：

Iterator i = new LinkedListExtension().iterator();
while (i.hasNext()) {
    System.out.println(i.next());
}
