同時錄製多個用戶

我的要求是錄製用戶的聲音並將其保存在服務器上（多個用戶同時）。這裏是我的代碼：同時錄製多個用戶

in = (InputStream) request.getInputStream();       
fos = new FileOutputStream(f1); 
int read = 0; 
while ((read = in.read()) != -1) { 
    fos.write(read); 
} 
fos.close(); 
in.close();

我正在試圖在同一時間記錄爲多個用戶的聲音，當出現以下異常，我不與單個用戶獲取此異常：

發佈您收到的錯誤消息。顯示堆棧跟蹤。 – user2339071

有什麼例外？ –

不要關閉InputStream對象。

拇指規則：如果您尚未打開連接或流，請不要關閉它。

評論in.close（）
