Java APIs

hey, i'm new to java, so bear with me here. ^.^

I'm working on a summer assignment for school. I've downloaded all of the files i've been told to download, and saved them in the files directed by my teacher. I've copied over the codes she's given us into JCreator, and I've posted the code below:

import chn.util.*;

public class StudentInfoDriver
{
public static void main(String args[])
{
StudentInfo student1 = new StudentInfo();

System.out.println("Student #1 Info \n");
System.out.println("Student's Name: " + student1.getName());
System.out.println("Student's Age: " + student1.getAge());
System.out.println("Student's Hobby: " + student1.getHobby() + "\n" );


StudentInfo student2 = new StudentInfo();
ConsoleIO keyboard = new ConsoleIO();

System.out.println("Enter your name");
String name = keyboard.readLine();
student2.setName(name);

System.out.println("Enter your age");
int age = keyboard.readInt();
student2.setAge(age);

System.out.println("Enter your hobby");
String hobby = keyboard.readLine();
student2.setHobby(hobby);

System.out.println("");
System.out.println("Student #2 Info \n");
System.out.println("Student's Name: " + student2.getName());
System.out.println("Student's Age: " + student2.getAge());
System.out.println("Student's Hobby: " + student2.getHobby() + "\n" );


System.out.println("Student #1 Info \n");
System.out.println("Student's Name: " + student1.getName());
System.out.println("Student's Age: " + student1.getAge());
System.out.println("Student's Hobby: " + student1.getHobby() + "\n");

}
}

and when i tried to compile it, i got this error:

C:\Program Files\Java\JCreator LE\MyProjects\StudentInfo\StudentInfoDriver.java:1: package chn.util does not exist
import chn.util.*;
^

i've checked, and i do have "chn.util" on my computer... how do i fix this?

thanks!
