import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

public class file {

 public static void main(String[] args) {
  try {
   FileInputStream f=new FileInputStream("src/com/imooc/io/speech.txt");
   int n=0,sum=0;
   
    while((n=f.read())!=-1){
     System.out.print((char)n);
     sum++;
     }
    System.out.println(sum);
    f.close();
   }catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
  catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
