1. A class which doesn’t have any name is called anonymous class and which is a type of inner class. It can be either member class or local class.
2. It is a sub class that extends a class or implements an interface but not both. It can implement only one interface.
3. These are used where implementation of methods various from one object to another object. Anonymous class is final class.
4. public class Demo{
A a=new A();
a.m1();
A 1=new A(){ void m1(){ --- }};
a1.m1();
}
