Identify and name the following tokens: (i) public (ii) 'a' (iii) == (iv) { }

(i) Keyword (ii) Literal (a character literal) (iii) Operator (a relational operator) (iv) Separator (punctuator)

A token is the smallest meaningful unit of a program. Java has five kinds, and this question walks through four of them: Keywords - reserved words with a fixed meaning (public, class, void, static) Identifiers - names given by the programmer (variable and class names) Literals - fixed values written in the code (25, 'a', "text", true) Operators - symbols that perform operations (+, ==, &&) Separators - punctuation that groups or ends code ({ } ( ) ; ,) Naming the sub-type, as in "relational operator", earns no extra mark but does no harm.
