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.  Refer to the program in your lab manual on page 21.  Write a program to do the following: (Getting Started with Pico)

• Read 3 numbers (grades) from the user.  Do not use the cs1.Keyboard class from the author.  Use the InputStreamReader and BufferedReader that Blanca taught in class.
• Parse the input Strings for numbers.  Keyboard input, even numbers, is brought in by the BufferedReader as a String.  You need to use the parseInt or parseDouble method to pull the integer number from the String. 
• Calculate the average of the three grades.
• At this point there is no validation so some wacky stuff may happen (with bad user input).  Later on in the course you will be asked to modify it to include if-statements for the number range, and asked to implement a try / catch statement for catching any exceptions thrown by the parse methods.
• Throughout your program, print user-friendly messages asking for and acknowledging the user input.  A good way to acknowledge the user input is to print a message after the user enters a number, and tell them the number they entered.
• After the three numbers are entered, parsed, and averaged, print a user-friendly message telling the user what the average of the three grades was.
• Create comments throughout the program to reflect what the program is doing.  For guidelines on formatting your code and for comments, see the Java Coding Standard .
   
• compile (UH UNIX command:  javac2 <filename.java>)
• run (UH UNIX command:  java2 <filename>)

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'. 

* 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 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.

4.  Your e-mail should have the following subject:  lab 4 / lastname  (lastname should be substituted for your lastname)  Not following this standard will result in a deduction of points.

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

6.  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

7. 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.
