ICS 111, Introduction to Computer Science
Lab 18 - Objects
Note: Only one lab for this week.
It will be due on Thursday at 11:59 pm.
Make sure that you logout from the computers when you leave
the lab or other persons may see your stuff or use your account to do "bad"
things.
Instructions:
To receive credit for this lab assignment, you must be finished by
Thursday, November 11, at 11:59 p.m. After this time you will not receive any credit. Future lab assignments will be due by 11:59 p.m. on the day of the lab assignment.1. Log in to UH UNIX (Secure Shell in Windows)
- If you are in the lab, go to the Start Menu, then Programs,
and look for 'SSH Secure Shell Client'. If you're at home, a good program to use to connect to
UH UNIX
is Putty (click here to download).
The putty program is an executable and doesn't need to be installed.
- Host name is: uhunix.its.hawaii.edu
- Your user name is the first part of your UH e-mail address.
If your UH email address is 'frank@hawaii.edu', your user name would be 'frank'.
Your password is the same as your e-mail password.
2. Create and edit a file in Pico (Getting Started with Pico), named Car.java and CarDealer.java
Do the following:
Write two classes, a Car class and a Driver class
called CarDealer.
--- for the Car class -----
The Car class should have the following instance
variables:
int iVIN //vehicle identification number
String sMake //car's make
String sModel //car's model
int iYear //car's year
double dPrice //car's price
write a constructor that will take initial values for
all the instance variables.
- Write the set methods for all the instance variables
- Write the get methods for all the instance variables
----- for the CarDealer driver class ------
Write a main method that will create the following
cars:
car1
int iVIN 12345
String sMake Ford
String sModel Mustang
int iYear 1981
double dPrice 7500
car2
int iVIN 5678
String sMake Cadillac
String sModel El Dorado
int iYear 1992
double dPrice 30000
car3
int iVIN 1023
String sMake Toyota
String sModel Del Sol
int iYear 1999
double dPrice 20000
print the make and model and year of all cars
modify car 1 to be from 1978
modify car 2 to be model CTS
modify car 3 to cost $12,500
print the make and model and year of all cars
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
You must also follow all of the commenting guidelines. Be sure to visit the link and check that your code follows all of the guidelines. Failure to do so will result in a deduction of points.
* Your program must compile without any errors, and must run properly to receive credit for this lab.
3. Get into Pine (Getting Started with Pine, PDF) and attach the Java (.java) file to an e-mail (See pages 11-12 in Getting Started with Pine, PDF).
- Send the file to ics111-lab@hawaii.edu account.
- control <J>, then control <T> allows you to browse and pick the file that you wish to attach. Only submit the .java file. Do not submit the .class file.
- Your e-mail should have the following subject: lab X / lastname (lab X should be substituted with the lab number, and lastname should be substituted for your lastname... e.g. Lab 5 / Sharritt). Not following this standard will result in a deduction of points.
4. Check the webpage to make sure that the e-mail arrived. Note that this will be sent to the ICS 111 lab address (ics111-lab@hawaii.edu). This one is different from the ics111-homework@hawaii.edu. There are two different ones so we can have homework assignments and lab assignments separate.

5. Once we (TAs) get the e-mail in our account AND we can verify it on the web, we will grade your lab. For grading policies on your lab, click here...
