我想用閱讀的java文件下面的代碼
public String readTemplateFile(String fileName) throws Exception
{
BufferedReader bufferedReader = new BufferedReader(new FileReader(fileName));
String line =null;
StringBuilder sb = new StringBuilder();
while((line = bufferedReader.readLine())!=null)
{
sb.append(line);
}
return sb.toString();
}
OR
public String readFile(String filepath) throws IOException {
File f = new File(filepath);
if (f.exists()) {
FileInputStream in = new FileInputStream(f);
int size = in.available();
byte c[] = new byte[size];
for (int i = 0; i < size; i++) {
c[i] = (byte) in.read();
}
String filedata = new String(c, "utf-8");
return filedata.toString().trim();
} else {
return null;
}
}
但充滿文件沒有得到如下讀 輸出

我很困惑，爲什麼我的代碼的行爲就像這可能有人plz幫助我解決這個問題。
在此先感謝
readFile使用InputStream.available（），就好像它返回文件大小一樣，但它沒有。閱讀該方法的javadoc。 – 2015-04-04 06:46:33
你的代碼在第一個區塊是好的。你最好把'sb.append（line）;'改成'sb.append（line +「\ n」）;'。你確定你閱讀的方式可能是錯誤的。你如何確定你得到了什麼？詳細說明'以下是輸出'。什麼輸出？ – greenapps 2015-04-04 13:44:00
