How to enter quotes in a Java string?

Not sure what language you're using (you didn't specify), but you should be able to "escape" the quotation mark character with a backslash: "\"ROM\""

In Java, you can escape quotes with \:

String value = " \"ROM\" ";

In reference to your comment after Ian Henry's answer, I'm not quite 100% sure I understand what you are asking.

If it is about getting double quote marks added into a string, you can concatenate the double quotes into your string, for example:

String theFirst = "Java Programming";
String ROM = "\"" + theFirst + "\"";

Or, if you want to do it with one String variable, it would be:

String ROM = "Java Programming";
ROM = "\"" + ROM + "\"";

Of course, this actually replaces the original ROM, since Java Strings are immutable.

If you are wanting to do something like turn the variable name into a String, you can't do that in Java, AFAIK.
