Java Fundamentals Hardening IO Stream Note 29:bufferedoutputstream/bufferedinputstream (byte buffer stream) Bufferedinputstream read data

1. Bufferedinputstream reading data

Bufferedinputstream construction method, as follows:

Construction Method Summary
BufferedInputStream(InputStream in) Create one BufferedInputStream and save its arguments, that is, the input stream for in future use.
BufferedInputStream(InputStream in, int size) creates a specified buffer size BufferedInputStream and saves its arguments, that is, the input stream for in future use.

2. code example:

1  Packagecn.itcast_05;2 3 ImportJava.io.BufferedInputStream;4 ImportJava.io.FileInputStream;5 Importjava.io.IOException;6 7 /*8 * Note: Although we have two ways to read, note that both of these methods can only be used in one code for the same object. 9  */Ten  Public classBufferedinputstreamdemo { One      Public Static voidMain (string[] args)throwsIOException { A         //Bufferedinputstream (InputStream in) -Bufferedinputstream bis =NewBufferedinputstream (NewFileInputStream ( -"Bos.txt")); the  -         //reading Data -         //int by = 0; -         //While (by = Bis.read ())! =-1) { +         //System.out.print ((char) by); -         // } +         //System.out.println ("---------"); A  at         byte[] Bys =New byte[1024]; -         intLen = 0; -          while(len = Bis.read (bys))! =-1) { -System.out.print (NewString (bys, 0, Len)); -         } -  in         //Freeing Resources - bis.close (); to     } +}

Run the effect as follows:
