Is there any possibility to retrieve scala.html file from java file which is contains raw data of HTML?

[krishna sai Charan]

I have a java file which contains scala.html data which is decompiled from a jar file. I did a lot of research to retrieve the sacal.html from java file but I didn't get any solution. I manually extracting code from java file and I cleaned up the code. I want a solution if we can directly convert the java file into scala.html.
