Having multiple perspectives open at the same time in Eclipse

I have a large screen and would like to show Package Explorer and Console (in Java and Debug perspectives respectively) in Eclipse at the same time.

I don't want to click on "Java" or "Debug" icon or select "Window --> show perspective --> ..." each time I want to switch between perspectives or see them.

Any ideas?

It's not quite possible as you describe in your question (each eclipse workbench only supports displaying one perspective), but the following options will give you a similar effect:

1. Open multiple eclipse windows, each using a different perspective. This isn't a great option though, which leads to...
2. (Recommended) - avoid perspectives entirely, and just open up all the relevant views, positioning them where you want.

I use option 2 myself - everything is open at the same time, and since you don't have things shuffling around or disappearing when you switch "perspectives", it's easy to train yourself to remember where specific views are.
