3.9 Keywords
The following character sequences, formed from ASCII letters, are reserved for use as keywords and cannot be used as identifiers (摟3.8):
Keyword: one of abstract default if private this boolean do implements protected throw break double import public throws byte else instanceof return transient case extends int short try catch final interface static void char finally long strictfp volatile class float native super while const for new switch continue goto package synchronized
The keywords const and goto are reserved, even though they are not currently used. This may allow a Java compiler to produce better error messages if these C++ keywords incorrectly appear in programs.
While true and false might appear to be keywords, they are technically Boolean literals (摟3.10.3). Similarly, while null might appear to be a keyword, it is technically the null literal (摟3.10.7).
3.10 Literals
A literal is the source code representation of a value of a primitive type (摟4.2), the String type (摟4.3.3), or the null type (摟4.1):
Literal: IntegerLiteral FloatingPointLiteral BooleanLiteral CharacterLiteral StringLiteral NullLiteral
