Question

How would i write this language in a parser in javaCC

7. Overwrite the .jj file with a grammar of your choosing. Your grammar should
have at least 4 production rules. Test that your parser works for the defined
language.
EBNF GRAMMAR CHOSEN:

EBNF language chosen:

time            =   time-of-day zone

time-of-day     =   hour ":" minute [ ":" second ]

hour            =   2DIGIT / obs-hour

minute          =   2DIGIT / obs-minute

second          =   2DIGIT / obs-second

zone            =   (FWS ( "+" / "-" ) 4DIGIT) / obs-zone

Explanation / Answer

**Use below code in parser**

date-time       =   [ day-of-week "," ] date time [CFWS]

   day-of-week     =   ([FWS] day-name) / obs-day-of-week

   day-name        =   "Mon" / "Tue" / "Wed" / "Thu" /
                       "Fri" / "Sat" / "Sun"

   date            =   day month year

   day             =   ([FWS] 1*2DIGIT FWS) / obs-day

   month           =   "Jan" / "Feb" / "Mar" / "Apr" /
                       "May" / "Jun" / "Jul" / "Aug" /
                       "Sep" / "Oct" / "Nov" / "Dec"

   year            =   (FWS 4*DIGIT FWS) / obs-year

   time            =   time-of-day zone

   time-of-day     =   hour ":" minute [ ":" second ]

   hour            =   2DIGIT / obs-hour

   minute          =   2DIGIT / obs-minute

   second          =   2DIGIT / obs-second

   zone            =   (FWS ( "+" / "-" ) 4DIGIT) / obs-zone
