2、缓冲流BufferedInputStream

  1. package pers.zaw.in;
  3. import java.io.BufferedInputStream;
  4. import java.io.File;
  5. import java.io.FileInputStream;
  6. import java.io.IOException;
  8. public class BufferedInputStreamDemo {
  9.     public static void main(String[] args) throws IOException {
  10.         File file = new File("E:\\IO流\\java\\1.txt");
  11.         FileInputStream f = new FileInputStream(file);
  12.         BufferedInputStream in = new BufferedInputStream(f);
  13.         int n = 0;
  15.         while ((n = in.read()) != -1) {
  16.             System.out.print((char) n);
  18.         }
  20.         in.close();
