任何人都可以在这里为我指出正确的方向吗？我有一个方法应该读取文件并显示该文件中的数据。我只能让它显示一行。我知道这很简单，我忽略了，但我的大脑很糊涂，我只是不断地挖一个更大的洞。
public static String readFile(String file) {
String data = "";
if (!new java.io.File(file).exists()) {
return data;
}
File f = new File(file);
FileInputStream fStream = null;
BufferedInputStream bStream = null;
BufferedReader bReader = null;
StringBuffer buff = new StringBuffer();
try {
fStream = new FileInputStream(f);
bStream = new BufferedInputStream(fStream);
bReader = new BufferedReader(new InputStreamReader(bStream));
String line = "";
while (bStream.available() != 0) {
line = bReader.readLine();
if (line.length() > 0) {
if (line.contains("<br/>")) {
line = line.replaceAll("<br/>", " ");
String tempLine = "";
while ((tempLine.trim().length() < 1)
&& bStream.available() != 0) {
tempLine = bReader.readLine();
}
line = line + tempLine;
}
buff.append(line + "\n");
}
}
fStream.close();
bStream.close();
bReader.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return buff.toString();
}
最佳答案
String line = null;
while ((line = bReader.readLine())!=null)
