java_ buffered stream (input stream of bytes)

. 1   / ** 
2  * java.iko.BufferedInputStream the extends the InputStream
 . 3  * BufferedInputStream: byte input stream buffer
 4  * constructor:
 . 5  * BufferedInputStream (in the InputStream): Create a BufferedInputSream and saves its argument, i.e., the input stream in, for later use
 . 6  * BufferedInputStream (the InputStream in, int size): Create BufferedInputStream with the specified buffer size and saves its argument, i.e., the input stream in, for later use
 7  * parameters:
 . 8  * the InputStream: input stream of bytes
 9  * may be transferred FileInputStream , the buffer flow will increase FileInputStream a buffer, to improve the reading efficiency of FileInputStream
 10  * int size: specifies the size of the internal buffer of the buffer stream, is not specified the default
 11  * use steps:
 12  * 1. Create FileInputStream object constructor binding data source to be read
 13 * 2. Create BufferedInputStream object constructor FileInputStream passing objects, improving the efficiency of
 14  * 3. BufferdInputStream read method reads the file object
 15  * 4. Release the resources
