Identifiers
Identifiers are the names provided by the programmer, and can be any length in Java. They must start with a letter, underscore, or dollar sign, and in subsequent positions can also contain digits.
A letter that can be used for a Java identifier doesn't just mean uppercase and lowercase A–Z. It means any of the tens of thousands of Unicode letters from any of the major languages in the world including Bengali letters, Cyrillic letters, or Bopomofo symbols. Every Unicode character above hex 00C0 is legal in an identifier. Legal Java identifiers shows some example valid Java identifiers.
