Curly braces in "new" expression? (e.g. "new MyClass() { ... }")

Question

What do the curly braces do there ?

handler1 = new Handler() {          public void handleMessage() {         } }; 

object = new Class_Name() {}; ? This syntax exists only on Android or Java also? And what is it called in Java? Thank for your helps.

Answer 1

This is the syntax for creating an instance of anonymous class that extends Handler. This is part of Java.
