Java string literals are enclosed in double quotes ("), never in single quotes. Character literals are enclosed in single quotes ('), never in double quotes. A one-character string is not the same as the single character. Escape sequences (\n, \t, etc.) are single characters. There are no triple-quoted strings or raw strings in Java.
Strings can be concatenated with the + operator. Any object, of any type, may be concatenated to a String; it will be automatically converted to a String (for objects, via their toString() method) before being concatenated.
In Python, # starts a single-line comment; in Java, // starts a single-line comment. Java also has multi-line comments, beginning with /* and ending with */.
In Python a docstring (documentation string) is a string, usually triple-quoted, just after a function or method header. In Java, a Javadoc comment begins with /** and ends with */, and is put just before a method header, class header, or variable declaration.
In Python, string can reside in a pair of single quotes as well as a pair of double quotes. It supports multiplication: "x"*3 is "xxx".
