Studio Studio performance evaluation during debugging

Question

I am new to Android Studio and trying to pull myself together.

My question is: how can I see the meaning of any expression that needs to be questioned?
For example, in the code below, how can I see the value of Message.getText() ?

  if (Message.getText() == null){ Message.setError("Invalid Message");flag=true; } 

I use Eclipse with PyDev, and there I had the opportunity to evaluate any expression during debugging using the print statement.
I'm just wondering if there is equivalent functionality in Android studio.
