输入流阅读器跳过一些文本

大家好，这是我的代码的一个发挥

public ItemList() throws Exception {
    //itemList = new List<Item>() ;
    List<Item> itemList = new ArrayList<Item>() ;

    URL itemPhrases = new URL("http://dl.dropbox.com/u/18678304/2011/BSc2/phrases.txt");     // Initilize URL
    BufferedReader in = new BufferedReader(new InputStreamReader(
            itemPhrases.openStream())); // opens Stream from html

    while ((inputLine = in.readLine()) != null) {
        inputLine = in.readLine();
        System.out.println(inputLine);
        Item x = new Item(inputLine);
        itemList.add(x);
    } // validates and reads in list of phrases
    for(Item item: itemList){ 
        System.out.println(item.getItem());
    }

    in.close();// ends input stream
}

我的问题是我正在尝试从 URL http://dl.dropbox.com/u/18678304/2011/BSc2/phrases.txt 但是当它打印出我收集的内容时，它只打印：

aaa

bbb

ddd

我尝试研究该库并使用调试器，但都没有帮助。

Hi guys so this is an exert from the code I have

public ItemList() throws Exception {
    //itemList = new List<Item>() ;
    List<Item> itemList = new ArrayList<Item>() ;

    URL itemPhrases = new URL("http://dl.dropbox.com/u/18678304/2011/BSc2/phrases.txt");     // Initilize URL
    BufferedReader in = new BufferedReader(new InputStreamReader(
            itemPhrases.openStream())); // opens Stream from html

    while ((inputLine = in.readLine()) != null) {
        inputLine = in.readLine();
        System.out.println(inputLine);
        Item x = new Item(inputLine);
        itemList.add(x);
    } // validates and reads in list of phrases
    for(Item item: itemList){ 
        System.out.println(item.getItem());
    }

    in.close();// ends input stream
}

My problem is that I am trying to read in a list of phrases from the URL http://dl.dropbox.com/u/18678304/2011/BSc2/phrases.txt but when it prints out what I have collected it just prints:

aaa

bbb

ddd

I have tried researching the library and using the debugger but neither have helped.

您应该从 while 循环内部删除 inputLine = in.readLine(); ，它会再次调用 readLine() 函数，从而跳过每一行。

你的循环应该是这样的：

while ((inputLine = in.readLine()) != null) {
        //this line must not be here inputLine = in.readLine();
        System.out.println(inputLine);
        Item x = new Item(inputLine);
        itemList.add(x);
    }

You should remove inputLine = in.readLine(); from inside the while loop, it calls readLine() function a second time, thus skipping every second line.

Your loop should look like this:

while ((inputLine = in.readLine()) != null) {
        //this line must not be here inputLine = in.readLine();
        System.out.println(inputLine);
        Item x = new Item(inputLine);
        itemList.add(x);
    }
