the answer must be in java. thank you Question 2 [8 points] Consider the class Class A below: class Class A implements Serializable{ int a; static int b; transient int c; String s; // Constructor public Class A (int a, int b, int c, Strings){ this.a = a; this.b = b; this.c = c; this.s = s; Complete the class Test to test the serialization and deserialization of the objects of class Class A. State the possible variable values following...
