I want to let the JLbale move with mouse,so i tried this:




This does not work, something wrong in line 33.

But when i tryed this that i move the code frome line 44 to line 48 and place them under line 33,it works. i find this called "anonymous inner classes", but i don't quite understand.


Who can explain this to me? Thanks!

Forman, have you discovered the Oracle tutorials? I suggest you start with the lesson on Nested Classes and work your way down to Anonymous Classes.

Use Java8 and you can dispense with 90% of your anonymous classes.
