java.util.Iterator但无法导入java.util.Iterator [英] java.util.Iterator but cannot import java.util.Iterator

问题描述

鉴于此代码

import java.util.Iterator;

private static List<String> someList = new ArrayList<String>();

public static void main(String[] args) {

    someList.add("monkey");
    someList.add("donkey");

    //Code works when I change Iterator to java.util.Iterator, but import      
    //is not possible?
    for(Iterator<String> i = someList.iterator(); i.hasNext(); ) {
        String item = i.next();
        System.out.println(item);
    }

}

我收到错误：Iterator类型不是通用的;它不能用参数参数化

I receive the error: The type Iterator is not generic; it cannot be parameterized with arguments

Eclipse告诉我导入java.util.Iterator与同一文件中定义的类型冲突。

Eclipse tells me that the import java.util.Iterator conflicts with a type defined in the same file.

我能解决这两个确切错误的唯一方法是调用我的类 Iterator 。我想如果你正在写一个关于迭代的小测试类，这将是一个容易犯的错误：

The only way I can get those two exact errors is to call my class Iterator. I suppose this would be an easy mistake to make if you were writing a little test class about iteration:

import java.util.Iterator;
import java.util.ArrayList;
import java.util.List;

public class Iterator {

    private static List<String> someList = new ArrayList<String>();

    public static void main(String[] args) {
        someList.add("monkey");
        someList.add("donkey");

        for (Iterator<String> i = someList.iterator(); i.hasNext();) {
            String item = i.next();
            System.out.println(item);
        }
    }
}

解决方案：不要做那。把它叫做别的。

Solution: don't do that. Call it something else.

尽管你试着猜测你的代码看起来很有趣，但是你在问题中发布了一个完整的例子是一个短暂的过程。我不排除有另一个代码示例产生这些错误，虽然我没有找到一个经过一些实验。
