Question

public class Student{
//constant
public static int SLOW = 1;
public static int MEDIOCRE = 2;
public static int BRIGHT = 3;

public static int studentCount = 0;

private String name;
private int age;
private int smarts;

//contructor.. has to have the same name as the class
public Student(){
name = "John Doe";
age = 18;
smarts = SLOW;
++studentCount;
}
//constructor.. this change the above private value
public Student(String name, int age, int smarts){
this.name = newName;
this.age = newAge;
this.smarts = newSmarts;
++studentCount;
}

public static void showCount(){
System.out.println(studentCount);
}

public void setName(String newName){
name = newName;
}

public String sleep(int t1, int t2){
return ("Sleeps for " + (t2 - t1) + " hours");
}

public int showSmart(){
return smarts;
}
}


import java.util.Scanner;
public class TestStudent{
public static void main(String[] arg){
Scanner in = new Scanner(System.in);
Student.showCount();
Student s1 = new Student("John Doe", 18, Student.SLOW);

//int x = in.nextInt();

s1.setName("Billy Bob");

System.out.println(Student.studentCount);

Student s2 = new Student("Mary Jane", 20, Student.BRIGHT);

System.out.println(Student.studentCount);

System.out.println(s1.sleep(1, 3));
System.out.println(s2.sleep(1, 7));
}


}
