Consider the JavaFX example HelloWorld.java (from the section Hello World, JavaFX Style from Getting Started with JavaFX). This sample creates a frame that contains a Say 'Hello World' button.

from anonymous class instances, we can access local variables and enclosing class’s members 3.2. Static Members Anonymous classes cannot have any static members except for those that are constant. For example, this won’t compile: newRunnable() {staticfinalintx=0;staticinty=0;// compilation er...
