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:  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 in Pico (Getting Started with Pico), named LabX.java (substitute the X for the lab number- e.g. Lab5.java)

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 diameter (use radius times two for diameter)
area = pi x (radius  squared)

Notes:

1. To compute 'radius squared', just multiply radius x radius
2. It would be easier for you to declare your variables as doubles (instead of floats like in your notes)

• 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.  For example, every time you open a new {, you should indent everything underneath it two spaces like the following:

  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.

Notes:  Don't forget that Java and UNIX are case sensitive.  Therefore 'helloworld.java' isn't the same as 'HelloWorld.java'.  Also, remember that your class name must match your file name.  If your class name is 'Frank' then your filename would be 'Frank.java'.  You would compile by typing 'javac Frank.java' and you would run the program by typing 'java Frank'.

* 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)

4.  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.  Only submit the .java file.  Do not submit the .class file.

5.  Your e-mail should have the following subject:  lab X / lastname  (lab X should be substituted with the lab number- e.g. Lab 5, and lastname should be substituted for your lastname)  Not following this standard will result in a deduction of points.

6.  Send the file to ics111-lab@hawaii.edu account.

7.  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.

Here are the URLs:
http://www2.hawaii.edu/~tp_200/bmf/ics111-homework.html
http://www2.hawaii.edu/~tp_200/bmf/ics111-lab.html

8. 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...

* Some may argue that it is easier to do this from WebMail or other e-mail programs.  If you e-mail your lab / homework from anything besides Pine, it means that you're not positive that it runs / works properly in UNIX.  This could result in large point deductions if your program doesn't work properly.
