Strictly speaking, this field is redundant, because the token type can always be deduced from the token value, e.g. iff the value begins with "'", then the type is TokenType.CHARACTER_LITERAL.

value

public final String value

The text of the token exactly as it appears in the source code.

Iff this token represents a keyword, true, false, null or an operator, then this string is interned, so that it can be reference-compared with other interned strings.
