一道java题·请求高手献策
我这儿有一道JAVA的题·是英文的·简单的英文···我自己不太会·
In the Assignment One you are required to implement a command-line version of the
software. Your software will allow a manufacturer to create a list of required inventory
based on what is scheduled for production.
Project glossary:
• Product (or product item) – something that is produced by the manufacturer.
• Inventory item (or just inventory) – something that is requited for the manufacturing
of a particular product.
Task
1.Describe the manufacturer, e.g. name, address, main products,
clients, suppliers. Suggest ten (10) possible inventory items. Suggest two (2)
potential issues with the manufacturer’s supply chain and how they could be
improved.
2.Allow one product to be an inventory for another product.
3.Collect user input regarding how many items of each product are scheduled
for manufacturing. Then, display a table of inventory items: name/description,
quantity/quality of each item. In the real world, the list could then be sent to
the purchasing department for ordering the items.
4.Read/write information regarding the currently available inventory from/to a
file.
Achievement
1. Draw a UML class diagram of your classes showing all public methods, e.g.
by using NetBeans.
Connect the classes with “IS-A” and “HAS-A” lines, see p177
Each class: is named by a noun ; is correctly identified as a class ; has
a reasonable set of public methods .
2.Display a menu of available commands.
3.Display a list of products that the manufacturer could produce.
4. Display a list of inventory required to manufacture a specific product.
5.Display th

时间动态显示
1.方法一 用TimerTask
利用java.util.Timer和java.util.TimerTask来做动态更新，毕竟每次更新可以看作是计时1秒发生一次。
代码如下：
import java.awt.Dimension;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.Timer;
import java.util ......
一、运行class文件
执行带main方法的class文件，命令行为：
java <CLASS文件名>
注意：CLASS文件名不要带文件后缀.class
例如：
java Test
如果执行的class文件是带包的，即在类文件中使用了：
package <包名>
那应该在包的基路径下执行，命令行为：
java <包名>.CLASS文件 ......

第七章 方法
方法的来源
方法的概念来源于数学上的函数，在数学中，当数据具有一定的规律时，就是用一个函数来代码该数字的规律，例如f（n）=n则代表1、2、3、……这样的一个数列。在数学上n是参数，对于确定的n值只有一个f（n）的值和它对应
方法是一组为了实现特定功� ......
JAVA程序员面试之葵花宝典
1、面向对象的特征有哪些方面
1.抽象：抽象就是忽略一个主题中与当前目标无关的那些方面，以便更充分地注意与当前目标有关的方面。抽象并不打算了解全部问题，而只是选择其中的一部分，暂时不用部分细节。抽象包括两个方面，一是过程抽象，二是数据抽象。
2.继承：继承是一种联结类的层次模 ......
