请问文件流有没有按行读取的方法

import  java.io.*;
class Example20_10
{ public static void main(String args[])
{ try{
  RandomAccessFile file=new RandomAccessFile("Example20_10.java","rw");
  long filePoint=0;
  long fileLength=file.length();
  while(filePoint<fileLength)
  {String s=file.readLine();
   System.out.println(s);
   filePoint=file.getFilePointer();
   }
  file.close();
  }
  catch(Exception e){}
}
}
