当创建一个类的对象时，将调用所有祖先的构造函数，该对象从类层次结构的顶部开始并向下移动

class MyClass extends MyBase {

    public MyClass() {

        super();  // Injected by the compiler 

        System.out.println("Inside CSub() constructor.");
        /** from 
        时 代 J a v a - N o w J a v a . c o m**/

    }

}

class MyBase {

    public MyBase() {

        super();  // Injected by the compiler 

        System.out.println("Inside CSuper() constructor.");

    }

}



public class Main {

  public static
