public class Husband extends Persona{
    /**第二执行
    public Husband() {
        super("One");
        System.out.println("Two");
    }
}

public class Wife extends Persona {
    /**第三执行
    public Wife(){
        super("Four");
    }
    /**第四执行
    public Wife(String name) {
        super(name);
        System.out.println("Three");
    }
}

public class Persona {
    private String name;
    private String sex;
    private Integer age;
    
    public Persona(String name){
        System.out.println("我的名字是："+ name);
    }
    /**省略Seter/getter

public class Test {
    /**
     * 静态块只执行一次/最先执行的
     */
    static {
        System.out.println("Here We Go");
    }
    /**第五执行
    public Test(){
        System.out.println("This just a test");
    }
    public static void main(String[] args) {
        Husband husband=new Husband();
        Wife wife=new Wife();
        wife=new Wife("Five");
        Test test=new Test();
        test.say();

    }
    /**最后执行
    public static void say(){
        System.out.println("Say Something");
    }
}
