History about the Java Language
This project will make sure that you have installed all of the class tools,
that you can check-out projects, save your work, and submit projects. You
may also learn a couple of interesting facts about Java.
This project allows you to read a little about the
historical development of Java from the web. You can get all of the
information you need from the web page at http://java.com/en/javahistory/timeline.jsp
-- use the information on that site to correct the information in the Java
source file provided on CVS. When deleting information that is not
correct, make sure you delete the slashes in addition to the incorrect names
Overview of What You Must Do For This
We have written a project called "Spring10Proj0", which has been
copied to your personal CVS repository. Your job is to do the following:
- Download and Install Java, Eclipse, and the course
plug-ins onto your computer (unless you are working in a lab on campus.)
- "Check out" the project. (That means copy
it from your CVS repository onto the computer you are working on using the
CVS Repository Perspective.)
- Using the Java Perspective, edit the project (as described
below and in the file itself) and then save your work.
- Run the project and read what is on the screen to make
sure it looks correct. If it is not correct, go back to #3.
- Submit the project for testing and grading. If you
haven't received all of the points from the submit server for this
project, go back to #3.
Detailed descriptions of these four steps follow:
1. Install the Course Tools
Detailed instructions for installing the course tools can be found by following
this link. (If you have already done this on the machine you will be
using for the project, there is no reason to do it again.) It is
important that you follow those instructions very precisely so that you will
have the correct versions of all of the tools. In a nutshell, you will do
- Install the correct Java version.
- Copy the Eclipse zip file to your computer.
- Extract the contents of the zip file, therefore having
Eclipse and its corresponding CMSC departmental plug-ins available for you
2. "Check Out" the Project
- Get your class account. If you have not
already done so, login to the grades server (grades.cs.umd.edu) to obtain your
class account and password. The account ID will have this
format: cs131xxx. (You will need your University of Maryland
directory ID and password to access the grades system.)
- Create a CVS Connection. If you have not
already done so, you will need to create a "CVS connection" in the
CVS repository perspective of Eclipse. You only need to do this once
on any particular machine that you want to work on. (The same CVS
connection can be used on that computer for the entire semester.)
Here's how to do it: After changing to the CVS repository
perspective, right-click the left-hand portion of the screen (under
the tab that says "CVS repositories") and select "New,
Repository Location". This will bring up a dialog box with lots
of things for you to fill in. Fill in the fields so that they look exactly
screenshot. You should use your class account ID in the two places
where it says "cs131XXX", and you should type the corresponding
password into the box that says password. Everything else
should be copied so that it looks exactly like the screenshot. Note
that the connection type must be changed to extssh.
- Check Out the project. Click the little
"+" (or triangle) next to the CVS connection that you
created. Then click the little "+" (or triangle) next to
the word "HEAD". You should be able to see an entry that
says "Spring10Proj0". Right-click this folder, and select
"Check Out". That will copy the project files to the
computer that you are working on.
3. Edit the Project and Save
- Switch over to the Java perspective. On the left
side of the screen (under the tab that says "Package Explorer")
you will see the project "Spring10Proj0". Click the little
"+" (or triangle) next to the folder. Now click the little
"+" (or triangle) next to "default package". You
should see a file called "JavaHistory.java". This is the
file you must edit! Double-click this file and it should open in the
editor on the right-side of the screen.
- Try running the program. Make sure that the file is
open in the editor, and then select Run, Run As, Java Application
from the menu at the top. You should see the output in the
"console" window at the bottom of the screen.
- Modify the contents of the file so that it has only
correct information. You need to make sure you remove all incorrect
information and slashes from the sentences. You will find more
specific instructions in the file itself -- you'll see what we mean when
you open the file.
- When you're done, save your work by clicking the little
disk icon at the upper left or by selecting "File, Save" from
the menu at the top.
4. Run the Project looking at the
Always run the project and make sure it looks correct to you before
submitting the last time. Make sure everything works as expected -- if
not, edit the file to repair it, save, and try running it again. If you
get stuck, drop by to visit one of us during office hours!
5. Submit the Project
- To submit, right-click the project folder (in the
"package explorer" window within the Java perspective) and
choose "Submit Project". If you do not see the
"submit" option, then your plug-ins were not installed
- Go to the submit server (submit.cs.umd.edu) to see if you
passed the tests. If you didn't pass the tests, fix up the project
source file, test it and then submit it again!
There are two public tests and five release tests that you
must pass for this project. Together these comprise 100% of the project
grade (since there will not be any portions that need to be graded by the TAs
for this project). You will get the points for the tests you pass - you
can know how many points you have by release testing your submission.
