Problem
Create a Java class, ObjUtil, that will provide object serialization and deserialization methods for use by any other class. This class has no constructor, as no object of the class will be created. Rather, the two methods, much like methods in the Math class, are called without an object. After creating and compiling the new class, test it by using its methods in place of the corresponding methods in the MakeDB and StockTrackerDB classes.
