Eclipse uses the term perspective to mean a saved configuration of views and their placement on the workbench. So far, you've seen only the "Java" perspective that is used when developing applications. This perspective contains things such as a task list, console output, and documentation views, but there is another important perspective that we will encounter next—the Debug perspective.
The views in the Java perspective aren't particularly useful when you are debugging an application, so they are hidden and an all new set of windows is displayed once you switch to the Debug perspective. These views include the call stack, variables, and watch windows that are more useful when trying to look at the current state of the running application. Let's take a look at that right now by going back to the simulator and finding that bug we made.
