java读文件，指定行开始到文件的最后

<pre name="code" class="java">方法一：

 public static void main(String[] args) throws Exception    {      

       String str = Test.getString(0);      

       System.out.println(str);   

 }   

 public static String getString(int index) throws Exception{        

       BufferedReader br = new BufferedReader(new FileReader(new File("aa.txt")));       

       StringBuffer sb = new StringBuffer();       

       String temp = null;        

       int count = 0;       

       while((temp = br.readLine() ) != null){            

             count ++;           

             if(count >= index){                

                   sb.append(temp + "\n");           

             }       

       }       

       return sb.toString();    

}

 

方法二：

<pre name="code" class="java">public String getLine(String fileName, int startLine) throws Exception{        

      StringBuffer sf = new StringBuffer();        

      LineNumberReader lnr = new LineNumberReader(new FileReader(fileName));        

      String buff = lnr.readLine();        

      while(buff!= null){           

         if(lnr.getLineNumber()>= startLine){                

             sf.append(buff);                

             sf.append("\r\n");           

         }           

         buff = lnr.readLine();       

      }       

      return sf.toString();    

 }
