2. Expand the Java method that implements the function V for Declarations so that it implements the additional requirement stated in Exercise 6.1 (Exercise 6.1) Expand Type Rule 6.2 for Declarations so that it defines the requirement that the type of each variable be taken from a small set of available types, ffloat, int, bool, char). Use the same rule style and abstract syntax for Declarations used in this chapter. 2.
