In eclipse, you can have two console views...
On the console view, you have a button called 'open console' (the most right button in the console view). If you click this and select option 3 (new console view), you will see two consoles.
If you right click on the console tab and click on 'detached' the console will be detached from the eclipse frame. (for Eclipse Juno, see the HRJ's comment below)
You can select which output you want to see on each console by clicking the 'display selected console' button (second button from the right on the console view)
与恶龙缠斗过久,自身亦成为恶龙;凝视深渊过久,深渊将回以凝视…
