read the html file in java

Question

In java i have to read multiple files to search some text . Files are containing large html data so its difficult to read the content of the html file with the help of following code . Is any direct method to fetch the content of a file using java . I am using the following code but its making my application slow suggest me the best alternate of it

try{
   FileReader fr=new FileReader("path of the html file");
   BufferedReader br= new BufferedReader(fr);
    String content="";
   while((s=br.readLine())!=null)
    {

     content=content+s;

    } 

     System.out.println("content is"+content);
   }
  catch(Exception ex)
   {

    }

Answer 1

String concatenation is always slow when done in a loop

You will need to change it to using a StringbBuilder and giving that StringBuilder a decent starting size.

FileReader fr=new FileReader("path of the html file");
BufferedReader br= new BufferedReader(fr);
StringBuilder content=new StringBuilder(1024);
while((s=br.readLine())!=null)
    {
    content.append(s);
    }
