java能实现can 协议吗，有例子吗，大神们
包名不能加汉字，你自己加合适的吧.....
interface CanFly {
public void Fly();
}
class Animal {
String name;
int age;
}
public class Bird extends Animal implements CanFly {
public Bird() {
this.name = "鹦鹉";
this.age = 3;
}
public Bird(String name, int age) {
this.name = name;
this.age = age;
}
新手如何学好java编程
首先初学者学习Java，应该从最基础的开始 ：
但是在学习的时候不要图快，要系统的学习一下，或者在了解Java这一门语言是干什么，有什么作用之后，在进行相应的学习：
Java基础：
1.了解Java的发展；
2. 了解Java虚拟机（JVM）基础知识，如何一次编译、多处执行；
3.Java程序如何编译和运行
4. Java中的变量
5. Java数据类型
6. Java运算符
7. Java中的if-else
8. Java中的Switch-Case
9. Java For循环
10。JavaWhile循环
11. Java中的do-while循环
12.do-while循环。Java Continue语句
13. Java Break语句
14、Java 多线程
15、数组
16、集合
17、面向对象三要素
随后进阶学习：
数据库
目前主流的两个数据库一个是MYSQL活Oracle，MYSQL是比较好学的，Oracle的操作要稍微复杂一些，我的建议是这两个数据库都必须学。数据库这块我认为没有什么特别难的。只要多练习就可以。
JavaWeb
这也是Java学习的主要内容，非常重要，包括Web前端的内容，比如HTML、CSS、JavaScript等前端常用基础。JSP、Server、xml、javabean等技术。
框架
这是Java学习过程中的难点，如果前面的Java的基础没有学过，后面的框架很难学，所以学习JavaSE的时候一定要掌握好。目前常用的框架是SSH、SMM、Springboot以及SpringCloud主要框架。学习Java可以上B站搜索我校的官方账号，高淇老师的Java300集免费观看！
等等，希望可以给大家带来帮助！
JAVA编程，求大神啊，感激不尽！
代码如下：
import java.util.Scanner;
public class App33 {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int[] numbers = new int[8];
for (int i = 0; i numbers.length; i++) {
while ((numbers[i] = scanner.nextInt()) = 0) {
System.out.println("请输入一个正整数: ");
}
}
int sum = 0;
int max = Integer.MIN_VALUE;
int min = Integer.MAX_VALUE;
for (int i = 0; i numbers.length; i++) {
sum += numbers[i];
if (numbers[i] max) {
max = numbers[i];
}
if (numbers[i] min) {
min = numbers[i];
}
}
float average = sum * 1.0f / numbers.length;
System.out.println("总和：" + sum);
System.out.println("平均值：" + average);
System.out.println("最大值：" + max);
System.out.println("最小值：" + min);
}
}
Java 简单编程！英语的求大神
写了一个简单的，应该满足你的要求：

import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import java.util.Scanner;
