9:26 PM 71% o AT&T; KAssn15 Assign15-2.docx Write an error-free Java program to do the following things. Implement a class called Person. A person has a name, gender and a birth year. Make a Class Student that inherits from Person. A student has a major, a gpa and a number of credit hours completed. Write the class declarations for Person and Student. The main0 module is shown below. You must write the class definitions, constructor(s) and method(s) to make the program work. The output from the given main0 is shown after main. Your output can be formatted differently be displayed. For example, when the Student information is displayed, the program show their name, gender, birth year as well as the major, gpa and credits till graduation. If the data has not been set via a method, then the default value is displayed. Remember to put the usual header at the top of the program and to submit via Canvas.

below code is working fine. please make sure to create 3 different files for Test.java, Person.java and Student.java
1. Test.java
public class Test {
public static void main(String[] args) {

p2.set("Susan Jones", "female", 1989);
studs[0].set("Betsy", "female", 1996);
studs[0].setStudent("economics", 3.5, 45);
studs[1].setStudent("science", 2.7, 93);
p1.setName("Sally Smith");
studs[1].setName("Tom Hommond");
p1.display();
System.out.println(p2);
System.out.println();
for (int j = 0; j < 2; j++) {
studs[j].display();
}
