Using jflex/cup, write java program of the following

Write a Java program (using JFIex/Cup) to interpret WAE expressions. The CFG for WAE expressions is given below: SEMI I {+ > I {- > I {with ( ) } | You will write a main program, called WAE. java, that prompts the user with WAE>. The user can enter a WAE expression at the prompt or type exit to exit the WAE interpreter. If the user enters a WAE expression, your program should verify that it is a valid expression. If the expression is valid, it should be evaluated and the value of the expression should be printed; Otherwise and error message should be reported. Sample Run: $ java wee WAE> (with (x 3) (with {y 4} {with (z 5)} {+ x {+ y z}} The value is 12 WAE> (with (x 3) (with (y 4) (+ y z) Syntax Error WAE> (with (x 3) (with (y 4) {+ y z} Semantic Error
