Question

what is incorrect about string declarations
String title="Today's Specials";

Answer 1

Nothing is wrong with the snippet as written for Java/C#/JavaScript/Python/etc. — double quotes are used for string literals and an apostrophe inside them is fine:

- Java/C#/JavaScript:
String title = "Today's Specials"; // valid (Java/C#), in JavaScript use let/var/const

Common things that do cause errors and how to fix them:

- Using single quotes in languages that require double quotes for strings (Java):
String title = 'Today's Specials'; // INVALID in Java — single quotes are for char
Fix: use double quotes (as you did) or escape if using a char: char c = '\'';

- Using single-quoted strings that contain an apostrophe without escaping (JavaScript/PHP allow single quotes):
let title = 'Today's Specials'; // ERROR because inner ' closes string
Fix: escape the apostrophe: let title = 'Today\'s Specials';
Or use double quotes: let title = "Today's Specials";

- In SQL, string literals use single quotes and an embedded apostrophe must be doubled:
SELECT 'Today''s Specials';

- Smart (curly) quotes can cause syntax errors — ensure you use straight ASCII quotes: " and '.

If you tell me the language and the exact error you see, I can give a precise fix.
