Including escape sequences as part of string values

Imagine what happens when the letter combination represented by an escape sequence (let's say, \n) must be included as a part of the string value. Let's modify our example, as follows:

<HTML> 
   <BODY> 
          <H1>\n - new line, \t - tab</H1>  
   </BODY> 
</HTML> 

In this case, you can escape the \n sequence by using another backslash, as follows:

String html =  "<HTML>" + 
                    "\n\t" + "<BODY>" + 
                        "\n\t\t" + "<H1>\\n - new line, \\t - tab</H1>"                         +  
                    "\n\t" + "</BODY>" + 
                "\n" + "</HTML>";

But, with the changes, it's getting difficult to read and understand the preceding code. Imagine a developer in your team writes such code. Let's see how you could make it more readable. 

As a workaround, you can define String ...
