A mathematician might define the successor function as succ(i) = i + 1. In Java, this function would have to be a method. The abstract definition of this method would be something like:

static abstract int succ( int i ); 

a) Give Java code that implements this function. Assume this is in a context where it can be done.

b) Give Java code that evaluates this function. Assume this is in a context where it can be done.
