Answer 1

Because double quotes delimit String values, naturally you must escape them to code a literal double quote, however you can do it without escaping like this:

System.out.println('"' + s + '"');

Here, the double quote characters (") have been coded as char values. I find this style easier and cleaner to read than the "clumsy" backslashing approach. However, this approach may only be used when a single character constant is being appended, because a 'char' is (of course) exactly one character.
