正确答案：C

正确的执行顺序是:父类Ｂ静态代码块->子类Ａ静态代码块->父类Ｂ非静态代码块->父类Ｂ构造函数->子类Ａ非静态代码块->子类Ａ构造函数
也就是说非静态初始化块的执行顺序要在构造函数之前。

class SuperClass{
private static String STR = "Super Class Static Variable";
static{
System.out.println("Super Class Static Block:"+STR);
}

public SuperClass() {
System.out.println("Super Class Constructor Method");
}
{
System.out.println("Super Class Block");
}

}
public class ObjectInit extends SuperClass{
private static String STR = "Class Static Variable";
static{
System.out.println("Class Static Block:"+STR);
}

public ObjectInit() {
System.out.println("Constructor Method");
}
{
System.out.println("Class Block");
}
public static void main(String[] args) {
@SuppressWarnings("unused")
ObjectInit a =new ObjectInit();
}
}

执行完之后可以看到顺序如下:
Super Class Static Block:Super Class Static Variable
Class Static Block:Class Static Variable
Super Class Block
Super Class Constructor Method
Class Block
Constructor Method
