How to Run the Eclipse IDE for the First Time
An integrated development environment (IDE) is a little like a word processor, but instead of composing documents, the Eclipse IDE helps you compose computer programs.
The first time you launch Eclipse, you perform a few extra steps. To get Eclipse running, follow these steps:
In Windows, the Start menu may not have an Eclipse icon. In that case, look in Windows Explorer (it’s File Explorer in Windows 8) for the folder containing the extracted Eclipse files. Double-click the icon representing the eclipse.exe file.
On the Mac, go to the Spotlight and type Eclipse in the search field. When Eclipse appears as the Top Hit in the Spotlight’s list, press Enter.
When you launch Eclipse, you see the Workspace Launcher dialog box, as shown in the figure. The dialog box asks where, on the computer’s hard drive, you want to store the code that you will create using Eclipse.
In the Workspace Launcher dialog box, click OK to accept the default (or don’t accept the default).
One way or another, it’s no big deal.
Because this is your first time using a particular Eclipse workspace, Eclipse starts with a Welcome screen, as shown in the figure.
Dismiss the Welcome screen.
In most versions of Eclipse, you can dismiss the Welcome screen by clicking the little x icon that appears on a tab above the screen.
A view of the main screen, after opening Eclipse with a brand-new workspace, is shown in this figure.
