public HelloA() {
System.out.println("HelloA");
}
{ System.out.println("I'm A class"); }
static { System.out.println("static A"); }
}
public class HelloB extends HelloA {
public HelloB() {
System.out.println("HelloB");
}
{ System.out.println("I'm B class"); }
static { System.out.println("static B"); }
public static void main(String[] args) {
