Recursive Descent Parsing in C++ and Java | #2

I need the following 'Recursive Descent Parsing' problem solved in BOTH C++ and Java. Full source code for both and console screen shots of it working are required.

Using the simplest possible technique to implement a recursive descent parser that recognizes strings in this language. Input should be from a file called in .dat and output should be to the console.

BNF grammar:

------------------------

A -> I = E

E -> T + E | T - E | T

T -> P * T | P / T | P

P -> I | L | (E)

I -> a | b | ... | y | z

L -> 0 | 1 | ... | 8 | 9

------------------------

An example session might look like this:

------------------------

String read from file: a=a+b-c*d

The string "a=a+b-c*d" is in the language.

String read from file: a=a**b++c

The string "a=a**b++c" is not in the language.

------------------------

IMPORTANT: You will not have to handle whitespace when parsing the string, i.e. " " and similiar are illegal characters in this language.
