BufferedInputStream

For faster reading you should use BufferedInputStream to wrap any InputStream. BufferedInputStream has two constructors that accept an InputStream: public BufferedInputStream(InputStream in) public BufferedInput Stream (Input Stream in, int bufferSize) For example, the following code wraps a FileInputStream with a BufferedInputStream. FileInputStream fis = new FileInputStream(aFile); BufferedInputStream bis = new BufferedInputStream (fis); Then, instead of calling the methods on fis, work with the BufferedInputStream bis.
