Hormones play important roles in maintaining homeostasis – fluid and electrolyte, aid-base and energy balances.

标准以太网指的是 ( ) A: 10 BASE 5 B: 10 BASE 2 C: 10 BASE T D: 100 BASE T

（6-2）定义如下Base类，能在(1)处正确调用Base的构造方法。 class Base{ int x,y; Base(int x){} Base(int x,int y){ //(1)调用Base的构造方法 } }

如何能使程序调用Base类的构造方法输出"base constructor"; class Base{ Base(int i){ System.out.println("base constructor"); } Base(){  } } public class Sup extends Base{ public static void main(String argv[]){ Sup s= new Sup(); //One } Sup() { //Two } public void derived() { //Three } }
