类型不兼容-找到java.util.Iterator(Lot)但需要java.util.Iterator (java.lang.String)

Question

我目前在迭代集合时遇到了一个问题。当我声明字段和构造函数，并尝试进入我的方法来迭代集合并打印出元素时，出现了以下错误。

类型不兼容-找到java.util.Iterator(Lot)但需要java.util.Iterator (java.lang.String)

这是我的代码。

public class Auction
{
// The list of Lots in this auction.
private ArrayList<Lot> lots;
// The number that will be given to the next lot entered
// into this auction.
private int nextLotNumber;

/**
 * Create a new auction.
 */
public Auction()
{
    lots = new ArrayList<Lot>();
    nextLotNumber = 1;
}
public void close ()
{
    Iterator<String> it = lots.iterator();
    while(it.hasNext()) {
        System.out.println(it.next());
}
}

Answer 1

尝尝这个

public void close ()
{
    Iterator<Lot> it = lots.iterator();
    while(it.hasNext()) {
        System.out.println(it.next());
}
