java - 数组/循环不输出主行

Question

我的代码有一个小问题，我不太确定如何修复它。基本上我试图将文件分成不同的行(帧)，然后将这些行输入到文件中，并继续打印它们。我的文件第一行永远不会打印。

public class Main {
public static void main(String[] args) throws IOException
{
    /*Switch switcherino = new Switch();*/
    Frame frame = new Frame();

    Scanner input = new Scanner(System.in);
    System.out.println("Enter the name of the file to process: ");
    String fileName = input.nextLine();

    FileInputStream inputStream = 
            new FileInputStream(fileName);
    InputStreamReader inputStreamReader =
            new InputStreamReader(inputStream,Charset.forName("UTF-8"));
    BufferedReader bufferedReader =
            new BufferedReader(inputStreamReader);

    try{
        String str = " ";

        while((str = bufferedReader.readLine())!= null){
            String words[] = str.split(" ");

            for (int i = 0; i < words.length; i++){
                words[i] = bufferedReader.readLine();
                    System.out.println(words[i]);
            }
        }
    }
    catch (IOException e){
        e.printStackTrace();
    } finally {
        try {
            if (inputStream != null)
                inputStream.close();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
}
}

我不想使用 ArrayList，因为它可能会更容易。

提前致谢!

文件:(switch.txt)

fa00 123123123abc 111111222222 data1
fa01 111111222222 123123123abc data2
fa03 444444444444 123123123abc data3
fa01 123123123abc 4353434234ab data4
fa99 a11b22c33d44 444444444444 data5

输出:(来自 System.println(words[i]);)

fa01 111111222222 123123123abc data2
fa03 444444444444 123123123abc data3
fa01 123123123abc 4353434234ab data4
fa99 a11b22c33d44 444444444444 data5

这是错误的逻辑:您阅读了该行，将其拆分为单词，然后继续打印它们 - 无需尝试阅读更多行

    while((str = bufferedReader.readLine())!= null){
        String words[] = str.split(" ");

        for (int i = 0; i < words.length; i++){
            words[i] = bufferedReader.readLine();
                System.out.println(words[i]);
        }
    }

用这个代替

    while((str = bufferedReader.readLine())!= null){
        String words[] = str.split(" ");

        for (int i = 0; i < words.length; i++){
                System.out.println(words[i]);
        }
    }
