案例分析之运行顺序

public class shunXu {
    private static shunXu d = new shunXu();
    private SubClass t = new SubClass();
    


    public shunXu(){
        System.out.println(4);
    }
    public static void main (String [] args){
        System.out.println("hello word");
    }

}
class SuperClass{
    SuperClass(){
        System.out.println("构造方法SuperClass");
    }
}
class SubClass extends SuperClass{
    static{
        System.out.println(1);
    }
    public SubClass(){
        System.out.println(2);
    }
}

运行结果：

1
构造方法SuperClass
2
4
hello word

static 修饰的总是伴随着类一块运行，t在d之前运算，因为d运行的时候t还没结束。

private static shunXu d = new shunXu();
    private SubClass t = new SubClass();
