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.

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:  uhunix2.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 called 'LabX.java' (substitute the lab number for X- where  is the number of the lab- such as 'Lab1.java') in Pico (Getting Started with Pico), then compile and run the program.

Do the following:

• Write a program to compute the perimeter AND the area of a circle.  The emphasis will be in following the JAVA coding standard and formatting a nice output that will tell the user exactly what is going on.

Formulas:  (the 'x' means 'times' as in multiplication, and radius squared means r²or r^2)
perimeter = pi x radius
area = pi x (radius  squared)
 

• Before you submit your code, make sure that your code is formatted cleanly.  Refer to the Java Coding Standard and make sure your code adheres to its rules.  Every time you open a new {, you should indent everything underneath it.  For example:

  public class HelloWorld {
    public static void main(String[] args) {
      System.out.println("Hello World!");
    }
  }

3.  Get into Pine and attach the file to an e-mail and send the e-mail / file to the ics111-lab@hawaii.edu account.

• Your e-mail should have the following subject:  labX / lastname / section  (X should be substituted for the lab number [such as lab 1], lastname should be substituted for your lastname, section should be substituted with the A for the afternoon section and M for the morning section)  Not following this standard will result in a deduction of points.
• control <J>, then control <T> allows you to browse and pick the file that you wish to attach

4.  Check the webpage to make sure that the e-mail arrived. 

Here is the URL:
http://www2.hawaii.edu/~tp_200/bmf/ics111-lab.html

5. 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.  For grading policies on your lab, click here...
