Explain the diffe
For the next three problems, consider the following class:
// Represents a university student.
public class Student (
private String name;
private int age;
9
11
}
}
...
public void setAge(int age) {
this.age age;
)
public Student (String name, int age) (
this.name = name;
this.age age;
Also consider the following partial implementation of a subclass of Student to represent undergraduate students a
a university:
public class Undergraduate Student extends Student {
private int year;
}
Can the code in the Undergraduate Student class access the name and age fields it inherits from Student? Can
it call the setAge method?
& Write a constructor for the Undergraduate Student class that accepts a name as a parameter and initializes the
Under Graduate Student's state with that name, an age value of 18, and a year value of 0.
7. Write a version of the setAge method in the Undergraduate Student class that not only sets the age but also
increments the year field's value by one.
