Student.java

public class Student

    /*
     * private modifier—the field is accessible only within its own class.
     * 
     * In the spirit of encapsulation, it is common to make fields private. This
     * means that they can only be directly accessed from the Student class. We
     * still need access to these values, however. This can be done indirectly
     * by adding public methods that obtain the field values for us:
     */

    private int age;

    public String getName()
