This assignment is about OOP: Given Human class (Human.java) , please write a Student class (Student.java). This Student class is one child class of Human. A test file (CIS365Hw2InheritanceTest.java) of using the Student class is also given. Here is the result of running the CIS365Hw2InheritanceTest.java Student 1: no name, 0 years old, no major (10 points)Student 2: John, 18 years old, Computer Science (10 points)******** After change ******** (5 points)Student 1: Mary, 22 years old, Math (20 points)Student 1: Mary, 22 years old, Computer Science (20 points)Hello, I am a Student, and my name is Mary (20 points) public class CIS365Hw2InheritanceTest { public static void main(String[] args) { Student stu1=new Student(); Student stu2=new Student("John",18,"Computer Science"); System.out.println("Student 1: "+stu1.getName()+", "+stu1.getAge()+" years old, "+stu1.getMajor()); System.out.println("Student 2: "+stu2.getName()+", "+stu2.getAge()+" years old, "+stu2.getMajor()); System.out.println("******** After change ********"); stu1.setName("Mary"); stu1.setAge(22); stu1.setMajor("Math"); System.out.println("Student 1: "+stu1.getName()+", "+stu1.getAge()+" years old, "+stu1.getMajor()); stu1.setMajor("Computer Science"); System.out.println("Student 1: "+stu1.getName()+", "+stu1.getAge()+" years old, "+stu1.getMajor()); stu1.greeting(); // Human.java public class Human { private String name; private int age; public Human() { name="no name"; age=0; } public Human(String str,int n) { name=str; age=n; } public String getName() { return name; } public int getAge() { return age; } public void setAge(int num) { age=num; } public void setName(String s) { name=s; } public void greeting() { System.out.println("Hello, I am a Human.
