Java Lab 1 -- Mastering the IDE for java

To do this assignment, I would suggest that you try the lab machines first before installing Java JDK and  Eclipse on your personal machine. We will do much of  the first couple of assignments in class.  

When you are comfortable with Java and Eclipse, then attempt to using your own machine} If you want to configure your personal machine to be similar to what is available in the labs, you may need to install and download the following before creating the project.
  1. (Typically not necessary on a Mac, as Mac OS X ``comes complete with a fully configured and ready-to-use Java runtime and development environment".) 
  2. Install the Java Development Kit (JDK 6 Update 27) from  {http://www.oracle.com/technetwork/java/javase/downloads/index.html}
  3. Install Eclipse. Download it from {http://www.eclipse.org/downloads/packages/release/helios/sr1} where I would suggest picking Eclipse Classic 3.6.1. (Version 3.6 is installed on the lab machines on campus. There are other versions with minor differences; if you have a preference, use the version you prefer.)

Following the directions for comppiling and runnign a program.  For practice, do the Hello project as in the example in the Eclipse tutorial.. Eclipse is an icon on the Lab Application tool bar. Click on it to bring up the IDE (interactive development environment).

Lab1 -- Make a project called FirstOne

Step 1  Launch Eclipse.  

Step 2 Make a workspace on your USB stick.  On my computer at home, my memory stick was in the I: drive.  This will vary from computer to computer.

If the Welcome to Eclipse window appears, close it.  You should see a window similar to this:

Step 3  Select File>New>Project 

Step 4  Click next.  Make a new project on your usb stick  called Lab1.     In the lab, that project should go on your memory stick. You should alsways keep a copy on your hard drive in the dorm. As you type in the name Lab1 you will see it also appear in the shaded contents box in the window

Step 5. Click finish.  You should see:

B.  This is #2 in the Short Intro to Eclipse -- Make a file

Step 1  Select New>Class from the File menu. For this assignment give it the name FirstOne.  You may see a warning that the use of the default package is discouraged.  Don't worry about it.  Then click finish.



You should see a screen similar to this one:


Step 2.  Enter the following code, making the changes appropriate for you! Note that you need to get rid of the code that Eclipse supplied for you, if any.
import java.io.*;

/***************************************************************
 * Filename: FirstOne.java
 * Author: Your name and your section (CS0- 02 or 01 F06)
 * Date: Today's date
 * Version: 1.0
 * Description: A Java version of  hello
*****************************************************************/
class FirstOne
{
  public static void main (String[] arg)
  {
          System.out.println("This will be my first Java Program");
      
  }
}

C.  Fix anything wrong

You may see problems in the problem window.  Remove the errors, and the save the file again.  Note that I have deliberately put an error in the text!

D.  Running

.  1. First time you run only.) From the Run menu select  Application and the project should be the current project (Lab1)
      Highlight Java Application





Click the Run buttom on the bottom of the window
F.  Printout of the successful run
Step 1:  With the window above open, simultaneously hold down the alt key and the PrintScreen key
Step 2:  Do NOT close Eclipse, but open up Word or another word processor
Step 3:  File>Paste and the screen will appear on your docoument
Step  4:  Insert your file with the java code -- in this case, FirstOne.java.
 Insert menu -- file
    Look in: -- Select your flash drive:, and the Lab1 folder -- probably in your workspace folder
    Files of type: -- select all files (*.*)
    Select  -- FirstOne.java
    Click on --  OK   -- you should see your Java program below the screen!
Step 5:  Save the word document on your memory stick in the folder with the code for this project.  Name is something like Lab1.doc
Step 6:  Close all projects open in Eclipse.  Use the icon on the bottom of the screen to safely eject your usb memory stick.

Hand in

  1. The printout as in Step F ..
  2. Include the picture from the run.
  3. Repeat these steps for the dollars to euros program in the text , including the prinf() statement on p. 235.  Be sure you have put in comments in the style as in tep 2 but which reflect the dollars/euros program.
