静态代码块及父类子类初始化顺序

class A {    public A(){        System.out.print("2");    }    static{        System.out.print("1");    }}class B extends A{    public B(){        System.out.print("4");    }    static{        System.out.print("3");    }}public class Test1{    public static void main(String[] args) {        new B();    }}

运行结果：1 3 2 4
