In his single topic exams, Dan says that anonymous classes cannot be static. But in the following example (which is also from the same exam), the anonymous class is static and the example compiles. How ?abstract class A {
private int x = 4;
private int y = 2;
public A(int i1) {x=i1;}
public int x() {return x;}
public void x(int x) {this.x = x;}
public int y() {return y;}
public void y(int y) {this.y = y;}
public void incY() {y++;}
public abstract int math();
}
class B {
static A a1 = new A(2) {
{incY();}
public int math() {return x()+y();}
};
public static void main(String[] args) {
System.out.print(a1.math());
}
}
