马克-to-win，Super是一个参考（或说指针）指向他紧邻的父类（见下面的例子）。Super is a reference of its neighbour superclass
So Use super to call superclass’s constructor
用super可以指向被隐藏的父类的同名成员。Use super to call superclass’s members that has been hidden by a member of a subclass.
3.1 super指向父类的成员
注 意： 下例中：子类和父类都有i，我们一共有两个i，用super可以指向前一个父类的i。 note that: in the following case, subclass and super class both have a i, so altogether they have two i.
例1.3.1
class AMark_to_win {
int i;
}
class B extends AMark_to_win {
int i;
public B(int x, int y) {
super.i = x;//AMark_to_win 的 i被赋值
i = y;//B的i被赋值
}
public void show() {
System.out.println("i in superclass: " + super.i);
System.out.println("i in subclass: " + i);
}
}
public class Test {
public static void main(String[] args) {
B b = new B(2, 3);。。。。。。。。。。
