3.9 Keywords
50 character sequences, formed from ASCII letters, are reserved for use as keywords and cannot be used as identifiers (§3.8).:
Keyword: one of
    abstract   continue   for          new         switch
    assert     default    if           package     synchronized
    boolean    do         goto         private     this
    break      double     implements   protected   throw
    byte       else       import       public      throws
    case       enum       instanceof   return      transient
    catch      extends    int          short       try
    char       final      interface    static      void
    class      finally    long         strictfp    volatile
    const      float      native       super       while               
       
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 (§3.10.3). Similarly, while null might appear to be a keyword, it is technically the null literal (§3.10.7).
