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:

• Given the following strings:
  • String sJava = "ICS111, introduction to JAVA"; //note the space between the comma and the i.
  • String sHello = "hello my friend"; //note the spaces.

   

• Use these strings to print the following to the screen:
  • print the length of the String sJava
  • print the length of the String sHello

   

• change all the letters "o" from the string sJava to the number 0, and print the string to the screen.

 

• Using only the given strings, they should build and print "Hello my Java ICS111" //note that the H is capital letter. Note that JAVA is not all capital letters

 

• Before you submit your code, make sure that your code is formatted cleanly.  Every time you open a new {, you should indent everything one tab (or 5 spaces) underneath it.  For example:

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

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

• 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.

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

5.  Send the e-mail / file to the 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-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. 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.
