刘艺编著的java教程的课本习题加例题代码 很有用哦！

public class FileIn{
  public static void main(String args[]){
    try{
     FileInputStream rf=new  FileInputStream("d:\\datafile\\file1.txt");
     int b;
     while((b=rf.read())!=-1)
       System.out.print((char)b);
     rf.close();
    }
    catch(IOException ie){
      System.out.println(ie);
    }
    catch(Exception e){
