In Java an identifier is composed of a sequence of characters, where each character can be either aletter, a digit, a connecting punctuation (such as underscore _), or any currency symbol (such as $, ¢, ¥, or £). However, the first character in an identifier cannot be a digit. Since Java programs are written in the Unicode character set (see p. 23), the definitions of letter and digit are interpreted according to this character set. Identifiers in Java are case sensitive, for example, price and Price are two different identifiers.
