构造器调用顺序

     构造器调用顺序：

    1、基类构造函数；

    2、申明顺序的成员初始化方法；

    3、导出类构造器。

class Bread
{
 Bread()
 {
  System.out.println("Bead()");
 }
}
class Sandwich
{
 Sandwich()
 {
  System.out.println("Sandwich()");
 }
}
class Cheese
{
 Cheese()
 {
  System.out.println("Cheese()");
 }
}
class SuperMeal extends Bread
{
 SuperMeal()
 {
  System.out.println("SuperMeal()");
 }
}
class Meal extends SuperMeal
{
 Sandwich sandwich=new Sandwich();
    Cheese cheese=new Cheese();
 Meal()
 {
  System.out.println("Meal()");
 }
 public static void main (String[] args) {
  Meal meal=new Meal();
        }
}

输出：

--------------------Configuration: --------------------
Bead()
SuperMeal()
Sandwich()
Cheese()
Meal()

Process completed.
