try {FileInputStream fi =new FileInputStream(new File("d:\\a.txt"));BufferedInputStream bf =new BufferedInputStream(fi);StringBuffer sb =new StringBuffer();    if(bf.available()>0){    int i  = 0;         while(i!=-1){ // 此处不能用fi.read!=-1 这样的话在加上下面的则相当于读了两次      i = bf.read();      sb.append((char)i);     }         }   bf.close();   System.out.println(sb.toString());   BufferedReader br = new BufferedReader(new FileReader("d:\\a.txt"));   String line = "";   while((line=br.readLine())!=null){   System.out.println(line);    }} catch (FileNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}
