Does Java support referential transparency? What about in static contexts like a? What about in object contexts like b? Explain using the following bits of code to explain your answer for each question. a) • static int a,b,c;//declaration • //some stuff happens • result1 = (fun(a) + b) / (fun(a) – c); • temp = fun(a); • result2 = (temp + b) / (temp - c); • /function signature • int static fun(int arg); %3D %3D b) • Employee a = new Employee(); • Employee b = new Employee(); • Employee c= new Employee(); • //some stuff happens • result1 = (a.fun() + b) / (a.fun() – c); • temp = a.fun(); • result2 = (temp + b) / (temp - c); • //function signature inside Employee: • int fun() %3D
