For the Linux lab machines.

1. After logging in, there should be an icon for MCS Applications.  Double
   click that.  Inside the window, there should be an icon for Eclipse, 
   double click it.

   Alternatively you could open up a terminal window (by single clicking the
   Terminal window icon) and enter:
   
   eclipse &

   and press the enter key

2. When the Workspace dialog bog appears, keep the default directory
   to store your work.  Then click ok

3. If you see a Welcome screen, click the X to the right of the word 
   Welcome in the tab.

   Choose File -> Close All if necessary to start cleanly.

4. File -> New -> Java Project

5. Enter a name for the project (e.g. Lab01) --- I recommend no spaces
   
   click Finish

6. If you get a Confirm Perspective Switch Dialog click Yes

7. Either 
   a) Left click on the package name in the "Package Explorer"
   (left panel) and do File -> New -> Class

     or 

   b) Right Click on the package name in the "Package Explorer"
   (left panel) and select New -> Class 
   
8. Source folder should be the package/project name

   For name enter a name like: HelloWorld (no spaces allowed) 
   leave only public chosen
   and 
   check public static void ...
   uncheck others
   click Finish

9. Now you should see a place to enter your Java code.  Eclipse
started the file for you.  Enter code in the main method --- that is,
between the two curly braces that appear after/below the main method
declaration: public static void main(String[] args)

10. After you enter your code, do the following to Save, Compile and
Execute your program.

  To save your source code:
    File -> Save (or just do Ctrl-S)

  Go to Project menu

 ******
  If Build Automatically is checked then click it to uncheck it.
 ******
  
  To build/compile your source code:
    Project -> Build Project
 
  To execute/run your program:
    Run -> Run As -> Java Application

  Click on the tab labeled "console" on the bottom to see the output of
  the program.

11. When you are finished using Eclipse, do:

    File -> Close All

    Right click on Project name in Package Explorer (left panel) and
    choose Close Project.

12. Your java program will be stored in a folder within the folder you
    specified (or left as default) at the Workspace dialog bog. 

    Inside a project folder will be src and bin folders.
    The source code (the .java file(s)) will be in the src folder and the compiled code 
    (the .class file(s).) will be in the bin folder.

    Often, you will need to send the .java files to your instructor via email.
