- 2. Objectives for this lesson At the end of this lesson, you should be familiar 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 2
- 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. 3
- 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. 4
- 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. 5
- 6. Console view This is a view – that shows your program output. Eclipse also shows errors and warnings here. It looks as shown below… 6
- 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. 7
- 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. 8
- 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. 11
