静态初始化块的执行顺序

class Root
{
static
{
System.out.println("Roota");
}
{
System.out.println("Rootb");
}
public Root()
{
System.out.println("Rootc");
}
}
class Mid extends Root
{
static
{
System.out.println("Mid1");
}
{
System.out.println("Mid2");
}
public Mid()
{
System.out.println("Mid3");
}
public Mid(String msg)
{
//ͨ��this����ͬһ�������صĹ�����
this();
System.out.println("Mid4" + msg);
}
}
class Leaf extends Mid
{
static
{
System.out.println("Leafx");
}
{
System.out.println("Leafy");
}
public Leaf()
{
//ͨ��super���ø�������һ���ַ��������Ĺ�����
super("Javao");
System.out.println("ִ��Leafz");
}

}

class TestStaticInitializeBlock
{
public static void main(String[] args)
{
new Leaf();

}

}

按最开始父类到最后子类的顺序，优先执行第一静态函数，然后继续按这顺序，执行每个类剩下的所有函数
