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:  uhunix.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:

• First, create an input file in pico.  You may call it whatever you want.  In that file, put the following:

  hello 54.239 12 Joe Frank
  63.123113 90098.23 Blanca 23 23432432
  blah this is
  23423 a sdafs 999.123 test
  book 1 56.1254 next car 7563
  testing
  102.36 house
   

• Have your program ask the user for a file to open.  If the file doesn't exist, the program should print a user friendly message and exit the program.
   

• If the file exists (we'll specify the input file above that you made), do the following steps:
   

  • Read a line of the file at a time, until there are no more lines in the file. 
     

  • For each line of the file, split up the line based on a space.   For instance, in the file above- the last line of the file contains two tokens:  "102.36" and "house".
     

  • For each token do the following:
     

    • Analyze each token of the file, and if it is a number, then write the number to an output file.  If the token is not a number, then write the token to the screen.
       

    • In between each line of input you read from the input file, output a line of dashes to your output file and to the screen (such as System.out.println("-----------------------------"); for the screen part), so that you can visually see in your output where each line of the input file starts and ends.
       

    • When you output tokens to either the screen or the file, print the number of tokens remaining on the line, as well as the line number of the input file that you are on. (Something like:  3 tokens remaining on line 2)
       

• Finally, print the total number of tokens that were numbers, and the total number of tokens that were not numbers.
   

• Note:  When you test your program you should try it without the input file so that you make sure that your program will not crash.  In other words, you try it with and without the file and make sure that your program works without crashing.
   

• Note:  If the program doesn't compile or if the program crashes you will get no credit.
   
• 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.

  * 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 Java (.java) file to an e-mail (See pages 11-12 in Getting Started with Pine, PDF). 

1. Send the file to ics111-lab@hawaii.edu account.
2. 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.
3. Your e-mail should have the following subject:  lab X / lastname  (lab X should be substituted with the lab number, and lastname should be substituted for your lastname... e.g. Lab 5 / Sharritt).  Not following this standard will result in a deduction of points.

4.  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

5. Once we (TAs) get the e-mail in our account AND we can verify it on the web, we will grade your lab.  For grading policies on your lab, click here...
