eclipse start

Launch Eclipse. A screen like this should appear, where you can choose which workspace to open.

The Launcher may not have this folder exactly but you can browse to it or type a 
similar name to create one (replacing the first xxx with your name and the second 
with the number of your course). Select Use this as the default and do not ask again.
If you do, Eclipse will automatically use this workspace next time you open Eclipse.
If you want to change the workspace later you can always go to File → Switch Workspace...
to be sent back to the Workspace Launcher window.You should now see Eclipse's Welcome screen:

Click on the arrow on the right to go to the workbench.

This is where you'll do most of your work in Eclipse.
