character literals are enclosed in ________; string literals are enclosed in ________.
String literals can be formed by enclosing, the character being represented, in double quotes. NOTE: Double quote characters, in string literals enclosed by double quotes, are represented as a pair of double quote characters.
'A'. 'a'. '9'. Double quotation mark. You can use Unicode sequences anywhere in your Java code, not just as character literals. As indicated earlier, identifiers can be composed of any Unicode character. In fact, comments, identifiers, and the contents of character and string literals can all be expressed using Unicode.
