父类和子类的构造方法的调用顺序

（1）Java例子：

package niukewang;public class Dervied extends Base {    private String name = "dervied";    public Dervied() {        tellName();        printName();    }        public void tellName() {        System.out.println("Dervied tell name: " + name);    }        public void printName() {        System.out.println("Dervied print name: " + name);    }    public static void main(String[] args){                new Dervied();        }}class Base {        private String name = "base";    public Base() {        tellName();        printName();    }        public void tellName() {        System.out.println("Base tell name: " + name);    }        public void printName() {        System.out.println("Base print name: " + name);    }}

（2）输出结果：

Dervied tell name: nullDervied print name: nullDervied tell name: derviedDervied print name: dervied
