Lab 2 - January 23


Note:  The login / password that you signed up for is for using the computers in the lab.  This user name / password is only for gaining access to the lab computers, and has nothing to do with logging into UH UNIX.  Also, be careful and 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.

To receive credit for this lab assignment, you must be finished by Sunday, January 26, at 10:00 p.m.  After this time you will not receive any credit.  Future lab assignments will be due by 10:00 p.m. on the day of the lab assignment.  For example, this lab would be due at 10:00 p.m., January 23.  Unless otherwise notified, this will be the last lab with an extended deadline.



1.  Login to UNIX (Secure Shell in Windows)
    - If you're at home, a good program to use to connect to UNIX is Putty (click here to download).  The putty program is executable and doesn't need to be installed.
    - Host name is:
    - Your user name is the first part of your UH e-mail address.  If your UH email address is '', your user name would be 'frank'.  Your password is the same as your e-mail password.

2.  Create a Java file using Pico (Getting Started with Pico)

3.  Type the hello world program. You can copy it from your "Programming with JAVA" book.  It is on section 1.6 page 11.

4.  Edit the file in pico (Getting Started with Pico)
Do the following:
    - type the program (save as
    - compile (UH UNIX command:  javac
    - run (UHUNIX command:  java HelloWorld)

5.  Modify the program, change 'Hello World' for 'Spring 2003'

6.  Modify the program to add a String declaration as follows (substitiute the -name of the student- for your name)
String s = "Hi -name of the student-, welcome to ICS111!!!"; System.out.println(s);

For me the output would be:
    Spring 2003
    Hi Matt, welcome to ICS111!!!

7.  Get into Pine (Getting Started with Pine, PDF)

8.  Attach the file to an e-mail (See pages 11-12 in Getting Started with Pine, PDF)

- control <J>, then control <T>allows you to browse and pick the file that you wish to attach

9.  Send the file to account.

10.  Check the webpage to make sure that the e-mail arrived.  Note that this will be sent to the ICS 111 lab address (  This one is different from the  There are two different ones so we can have homework assignments and lab assignments separate.

Here are the URLs:

11.  Once I (TA) get the e-mail in my account AND I can verify it on the web, you will receive your lab participation point.


* Some may argue that it is easier to do this from WebMail. If you e-mail your homework from webmail, it means that you're not positive that it runs / works properly in UNIX.  This could result in point deduction if your stuff doesn't work properly.
