In Java, \\\' denotes a single quotation mark (single quote) character, and \\\" denotes a double quotation mark (double quote) character.
\\\'
\\\"
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 = '\'';
