Task 1: Create a new Eclipse Java project titled Chapter1

1. File | All Programs | Computer Classes | Eclipse 3.3
   • You will likely be asked to define a "Workspace" -- which is simply a place to store your files and settings. Use the eclipse directory you created in Lab 0, which should be at k:\cosc181\eclipse\
2. File | New | Java Project
   • Type Chapter1 as the Project Name
   • click Finish

Task 2: Create a Java main class titled HelloWorld within project Chapter1

1. Highlight Chapter1 in the Project Explorer along the left
2. File | New | Class
   • Make sure Source folder is Chapter1/src
   • For Name type HelloWorld (just like that -- no space, uppercase 'H' and 'W')
   • check the box next to public static void main(String[] args)
   • click Finish

Task 3: Add code to HelloWorld to make it display "Hello World!"

1. Place the cursor at the end of the line that reads //TODO Auto-generated method stub
2. Hit Return, then type System.out.println("Hello World!");
3. File | Save
4. Run | Run
   • Along the bottom, you should see a "Console" tab with the output "Hello World!"

Task 4: Add a standard class header comment to HelloWorld.java

1. Copy and paste the following lines before the line that starts public class HelloWorld {

/**
* HelloWorld displays a generic message to the console.
*
* @author Gene Rohrbaugh
* @version 1.0 8/29/2009
*
*/

2. Change the author to your name and the date to today's date

Task 5: Take a screen shot of a successful run of your program

1. Run the program ( Run | Run ), then take a screenshot of the Eclipse window ( Alt-PrntScrn ) , then save it as k:\cosc181\lab\lab11_lastname\HelloWorld.jpg

Task 6: Copy your java source file into the submission directory

1. go to k:\cosc181\eclipse\Chapter1\src\

2. right click on the Java source file HelloWorld.java and select Copy (alternatively, you could select the file and type ctrl+c to copy)

3. go to k:\cosc181\labs\lab01_lastname and paste ( Right-click | Paste or Edit | Paste )

4. The directory should now contain two files: HelloWorld.jpg and HelloWorld.java.

Task 7: Prepare and submit your lab

1. Virus-scan the folder containing your files ( lab11_lastname )
2. Compress the folder to a zip file named lab11_lastname.zip
3. Upload the zipped directory to Sakai
4. Submit the assignment
