static blocks

[Puneet Hattalli]

public class B {

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




public class Test extends B{

static int value;
static {
value = (int)(Math.random()*40);
System.out.println("static with value "+value);
}

public Test() {
System.out.println("constructor");
}

public static void main(String[] args) {
Test t = new Test();

}
}

In above piece of code, why is it that the static block in super class executes first?
Why not the static block from the class containing main?

Because it's loaded first. Certainly the class loader or the JVM sorts that sort of stuff out.

Is there any specific reason you feel you need to know this? It's very obscure.

Following code might help

class A{
    static{
        System.out.println("Static block of A");
    }
    {
        System.out.println("Non-static block of A");
    }
    A(){
        System.out.println("Constructor of A");
    }
    
}
class B extends A{
    static{
        System.out.println("Static block of B");
    }
    B(){
        System.out.println("Constructor of B");
    }
    {
        System.out.println("Non-static block of B");
    }
}
class C {
    static{
        System.out.println("Static block of C");
    }
    public static void main(String[] args) {
        B b = new B();
    }
}

Output:
Static block of C
Static block of A
Static block of B
Non-static block of A
Constructor of A
Non-static block of B
Constructor of B

Thanks For the Reply.
Actually i was learning inheritance topic.
I was confused because I thought since main method is the entry point of execution, it would execute code from the static block of main()
method in Test class.
So thanks again for the reply, now I know that since Test Class extends B Class the static blocks of B class are executed first.
