Storing html file in a String in java

I am sending emails using amazon java sdk. I have to send html template as mail. I have written a program for this and it is working fine. But now I am storing the whole html code in a single String. But whenever i need to edit the template, I have to edit the program (I mean the String variable). And also I have to take care the special characters like " \ ...etc in that html code. Please suggest me an elegant way to solve this issue.

Better and easiest way is reading the html file line by line using simple file reading operation and append this each line to a single String. And also I found this solution (also a better one, if you are ready to add one more library file to your project) from SO.

Check the Apache Velocity Project. You can create template for several things. From it's user-guide page

Velocity can be used to generate web pages, SQL, PostScript and other output from templates. It can be used either as a standalone utility for generating source code and reports, or as an integrated component of other systems.

You can use a VTL(Velocity Template Language) . A example from above link 

<HTML>
<BODY>
Hello $customer.Name!
<table>
#foreach( $mud in $mudsOnSpecial )
   #if ( $customer.hasPurchased($mud) )
      <tr>
        <td>
          $flogger.getPromo( $mud )
        </td>
      </tr>
   #end
#end
</table>

Use Apache Common Lang api's StringEscapeUtils#escapeHtml, It escapes the characters in a String using HTML entities and return a new escaped String, null if null string input.

For example:

"US" & "UK"

becomes:

&quot;US&quot; &amp; &quot;UK&quot;.

Use a template engine for that and store your template externally either in class path or on a file system. Here is a question that may help you selecting one: https://stackoverflow.com/questions/2381619/best-template-engine-in-java
