Regular Expression Parsing In Java

[ArdGre]

Hi,

My program must take a regular expression as input and be able to tell
whether its a valid one or not.

In doing so I am not allowed to use any inbuilt java libraries but have
to create my own context free grammar to parse it.

The regular expression can contain parantheses, kleene closure and
union operator ( that is '|' ).

Please help.

Regards,
Arvind

Investigate the parsing techniques your class has recently studied.
Determine which would be useful here. Apply them.

Competitive isn't the word.

I'll have to remember in case I get stuck. Are you on PayPal?

No I'm not on PayPal. I did private tutoring at the college where I was
studying, and took cash/checks.
