至于网页的代码嘛,这里就不贴了。你要的话HI我吧^_^。
JAVA代码如下:

}
}
效果如下图:
代码如下
/**
* Author: zhyx
* Date:2017/11/30
* Time:8:56
*/
public abstract class Contailner {
double r;
abstract double volume();
}
/**
* Author: zhyx
* Date:2017/11/30
* Time:8:57
*/
public class Cube extends Contailner {
public Cube(double r) {
this.r=r;
}
@Override
double volume() {
return r*r*r;
}
}
/**
* Author: zhyx
* Date:2017/11/30
* Time:9:01
*/
public class Sphere extends Contailner {
public Sphere(double r) {
this.r=r;
}
@Override
double volume() {
return 4/3*Math.PI*r*r*r;
}
}
/**
* Author: zhyx
* Date:2017/11/30
* Time:9:02
*/
public class Tiji {
public static void main(String[] args) {
Cube cube=new Cube(4);
System.out.println("立方体体积为:"+cube.volume());
Sphere sphere= new Sphere(4);
System.out.println("球体体积为:"+sphere.volume());
}
}
用Java编写一个员工类程序:1.属性:员工编号,员工姓名,基本工资,奖金,2.构造方法:至少两个。如下:
package com.test;
public class Employee {
/**
* 员工编号
*/
private String number;
/**
* 员工姓名
*/
private String name;
/**
* 员工薪水
*/
private double salary;
/**
* 无参数构造函数
*/
public Employee() {
}
/**
* 给属性赋值构造函数
* @param number
* @param name
* @param salary
*/
public Employee(String number, String name, double salary) {
super();
this.number = number;
this.name = name;
this.salary = salary;
}
public static void main(String[] args) {
//员工一,并且构造函数里设置值
Employee e1 = new Employee("e0001", "xiaoming", 5000.0);
System.out.println("员工一:" + e1);
//员工二,用set设置值,get的话可以获取到员工某个属性
Employee e2 = new Employee();
e2.setName("小二");
e2.setNumber("e0002");
e2.setSalary(5500.1);
System.out.println("员工二:" + e2);
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public double getSalary() {
return salary;
}
public void setSalary(double salary) {
this.salary = salary;
}
@Override
public String toString() {
return "Employee [number=" + number + ", name=" + name + ", salary=" +
salary + "]";
}
}
运行结果:
员工一:Employee [number=e0001, name=xiaoming, salary=5000.0]
员工二:Employee [number=e0002, name=小二, salary=5500.1]
1、代码能力
代码能力是基本功,Java语言本身,包括语言的各个方面包括对并发的理解,对内存使用对理解,对Java运维的理解等等,语言本身外,社区里常用的框架是否可以十分清晰的了解,包括spring,包括他实现的ioc,aop,orm,web机制是否有清楚的认识,有丰富的经验等等。
2、对常用中间件的理解
毕竟在一个大系统中,各种中间件是是否常见的,缓存中间件,消息中间件,例如
redis、memcache、rmq这些,要理解常用中间件使用场景,使用姿势(例如redis的常用命令),甚至包括他的一些运维,一旦出了问题,除了专门的运维人员,也需要你参与问题的排查,因为有时候这些中间件出现问题,是不当的使用姿势引起的。
3、架构、业务落地能力
前面提到了语言本身,各种中间件,如果你有很好的业务抽象能力和架构思维,就可以把一款部门内部产品很好的设计并实施了,这点蛮难的,想必都有过接手现有项目的经历吧,有时候真恨不得把之前的设计者拿出来批斗,作为一个设计者,你能否做到当下一个接手它的人会说一句,这个系统设计的真好,稳定又可拓展,理解起来也很容易。
4、沟通协作
毕竟一个部门内部产品,是不可能由一个人完成的,所以需要沟通协作,把设计好的方案,要和2-3个小伙伴一起实施,包括同样身份的后端人员,前端人员,产品等角色,这个级别的人可能会参与带2-3个人,例如应届毕业等,所以你自己对知识的把握,分享精神,leadership都是很好的加分项。
