ICS 111, Introduction to Computer Science
Lab 4 -
String Permutations - February 1

This lab will help the student by:

Note:  The login / password that you signed up for is for using the computers in the lab this semester.  Please write down your username and password and keep it in a safe place, since you will need this for every lab this semester..  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.

Instructions:

To receive credit for this lab assignment, you must be finished by Wednesday, February 2, at 11:59 p.m.  After this time you will not receive any credit.  Future lab assignments will be due by 11:59 p.m. on the day of the lab assignment.

1.  Log in to UH UNIX (Secure Shell in Windows) or (Putty). 

2.  Create a Java file in Pico (Getting Started with Pico) that fulfills the following requirements:

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 'javac2 Frank.java' and you would run the program by typing 'java2 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.

- Your e-mail should have the following subject:  lab X / lastname  (substitute the lab number for 'X', and 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:

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.
