Define an abstract class Person that describes a typical person. Include methods to retrieve the person’s name, and to get or change his or her address. Next, define a subclass Student that describes a typical student. Include methods to retrieve his or her ID number, number of credits completed, and grade point average. Also, include methods to get or change his or her campus address. Finally, derive from Student a class UgradStudent for a typical undergraduate student. Include methods for retrieving his or her degree and major.

public abstract class Person {

   private String name;
   private String address;

   public Person(String name, String address) {
       this.name = name;
       this.address = address;
   }

   public String getName() {
       return name;
   }

   public String getAddress() {
       return address;
   }

   public void setAddress(String address) {
       this.address = address;
   }

   @Override
