In Java, \\\' denotes a single quotation mark (single quote) character, and \\\" denotes a double quotation mark (double quote) character.
You don't need to escape the ' character in a String (wrapped in "), and you don't have to escape a " character in a char (wrapped in ').
It's best practice only to escape the quotes when you need to - if you can get away without escaping it, then do!
The only times you should need to escape are when trying to put " inside a string, or ' in a character:
String quotes = "He said \"Hello, World!\"";
char quote = '\'';
