with the following Eclipse terminology
1. workspace
2. project
3. view
4. Console view
5. Package Explorer view
6. Navigator view
7. Editor view
Also you will know a bit about the Eclipse Menu

3. Workspace
 The Eclipse WORKSPACE is a directory or a folder where
eclipse stores your code for all your projects. Any time you
create an Eclipse project or file – it gets stored in this folder.
 You should NEVER modify files in the workspace directly
from outside the Eclipse environment.
 You can use ONE workspace for all of your coms207 work.
 You can create more than one workspace – maybe for
outside class work.

4. Project
 An Eclipse project is basically a folder where all code
for a single application is stored. This single application
can have many Java programs in it.
 You create Eclipse projects INSIDE the workspace.
You may be working on several projects – say, a Maze
project and a TicTacToe project. You will put all of them
in the same workspace.
 Important:
 Note that Eclipse allows you to create many types of
projects: for example: ordinary projects, web projects,
java projects, etc .
 You will be creating only JAVA projects. When you do
that, Eclipse will know what settings to use to compile
and run your programs.

5. View
 When you open Eclipse, it has several different parts
each of which show different information or in a
different way. Each such part is called an Eclipse view.
 There are many many views available and you can
select which views you want to open.
 You can close by clicking on x next to the name of the
view.
 Some of the more useful views are the:
 console view,
 package explorer view,
 navigator view, and
 editor view.


6. Console view
 This is a view – that shows your program output.
Eclipse also shows errors and warnings here. It
looks as shown below…

7. Navigator View
 This is a view - that
shows the folder structure
in your project. If you
opened the folder using
WINDOWS EXPLORER
(or Mac Finder), you
would see the exact
same folder structure.
 If you double click on a
file, it opens it in a editor.


8. Package Explorer View
 This is a view that shows
Java programs in your
workspace in a JAVA-like
manner (we will discuss
later).
 It does NOT show all the
folders. Instead, it shows
the classes and
packages in your project.
If you double-click on a
class – it opens it in the
editor.

9. Editor view
This view allows you to enter and make changes to
your Java programs. You can click on a tab to bring a
particular file to the forefront. 9

10. Eclipse Menu
 The Eclipse menu allows you to control all
operations in Eclipse. Here is a brief description of
the main menus.
 File menu – create new projects, save projects etc.
 Edit and Source menus – helps in editing a program.
 Run menu - offers you ways to execute a program.
 Window menu – allows customization
 Project menu – set project settings.
 10

11. Summary
 all projects are stored in WORKSPACE.
 all code for an application is stored in a PROJECT.
 a VIEW is just a part of the entire Eclipse window.
 the program output is shown in CONSOLE view
 folders and files are shown in NAVIGATOR view
 code to be edited is shown in EDITOR view
 folders/files shown in Java-like manner in Package
Explorer view
 Eclipse Menu allows you to control all operations.
