JAVA - 将句子写入文本文件

Question

我在下面有这个代码。基本上我从给定的网址获取输入。这个网站显示了一个句子。每次我重新加载网站时，它都会得到一个新句子等等。所以，我设法让它发挥作用。现在我正在尝试将句子写在文本文件中。但有些不对劲。它只写第一行，没有其他内容。我的代码有什么问题吗？

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

public class ReadIp {
public static void main(String[] args) throws MalformedURLException, IOException,     
InterruptedException {
    ReadIp readIP = new ReadIp();
    while (true) {
        readIP.getIP();
        Thread.sleep(2000);
    }
}

BufferedReader      buff;
InputStreamReader   inStream;
String              line;
URL                 url;
URLConnection       urlConn;
FileWriter fileWriter ;
BufferedWriter bufferedWriter;

public ReadIp() throws IOException {
    fileWriter = new FileWriter("myfile.txt", true);
    bufferedWriter = new BufferedWriter(fileWriter);
}

public void getIP() throws MalformedURLException, IOException {
    this.url = new URL("http://test.myrywebsite.co.uk");
    this.urlConn = this.url.openConnection();
    this.inStream = new InputStreamReader(this.urlConn.getInputStream());
    this.buff = new BufferedReader(this.inStream);

    try {
        while ((this.line = this.buff.readLine()) != null) 
        {
            System.out.println(this.line);
            try {
                this.bufferedWriter.write(this.line);
                this.bufferedWriter.write("\n");

                this.bufferedWriter.flush();

            } catch (IOException e) 
            {
            } 

        }
        if (this.bufferedWriter != null) 
        {
            this.bufferedWriter.close();
        }

       this.inStream.close();

    } 
    catch (Exception ex) 
    {
    }


}
}

任何帮助将不胜感激。谢谢。

移动语句

writer.close();

在内部 try catch block 之外，以便在将第一个条目写入文件后不会关闭 OutputStream。这同样适用于InputStream

inStream.close();
