Implement a Java application that connects to the database. The application employs a the following class inheritance hierarchy: С. Person; BrotherInLaw is_a Person; Class Person: Class Persons is the hierarchy's superclass and inherits the Java class Object. A Person's object is defined by the attributes of the Persons entity set in family E-R diagram. The class includes appropriate constructors and methods, including methods that perform the following operations: setPerson – inserts a person in the database; b. а. getXPerson – returns the X attribute of a person; and toString overrides the method toString in Object. с. returns the Person's object description as a String. The method Class BrotherInLaw: Class Persons BrotherInLaw inherits class Person, includes appropriate constructors and methods, including methods that perform the following operations: - executes the queries and return a list of the persons who are the executeQuery brothers-in-law of a given person; and b. а. print –…
