The safest way to rename a package or class in your project is to change its name through the Package Explorer window, not in your code.

1. In the Package Explorer window, right-click on the class or package and choose Refactor > Rename...:

   

2. The Rename window appears. Change the name of your class/package, then hit the Finish button:

   

3. If a window appears reporting problems, hit the Finish button.

   Unless you gave the class or package an invalid name, Eclipse safely changes its name in your code, as well as its file name in the Package Explorer.

1. Right-click on the method or variable you want to rename and choose Refactor > Rename...:

   

2. Eclipse highlights the name for you. Type the new name of the method/variable, then hit the Enter key:

   

   Unless you give the method or variable an invalid name, Eclipse safely changes all occurrences of it in your code.

If your Eclipse workspace appears "messed up" - windows missing, out of place, or collapsed - the easiest way to get things back in order is to reset the workspace's perspective.

1. Go to the Window menu > Perspective... > Reset Perspective...:

   

2. Hit the Yes button to reset the perspective to the default layout.
