- 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 –…arrow_forwardImplement the following hierarchy shown in Figure 1, using Java Inheritance. The class Student is the parent class. Note that all the variables are private and hence the child classes can only use them through accessor and mutator methods.arrow_forward
