是什么结果呢

class A {
{
System.out.println("A-1");
}

public A() {
System.out.println("A");
}

static {
System.out.println("A-static");
}

{
System.out.println("A-2");
}

}

class B extends A {
{
System.out.println("B-1");
}

public B() {
System.out.println("B");
}

static {
System.out.println("B-static");
}

{
System.out.println("B-2");
}

}

public class Test {
public static void main(String args[]) {
B b = new B();
                  System.out.println("-----------");
A a=new A();
}
}
