Java第二次作業(yè)第十六題

1、精選優(yōu)質(zhì)文檔-傾情為你奉上Java語言課程作業(yè)(第二次)題 目 第十六題 學(xué) 院 計(jì)算機(jī)學(xué)院 專 業(yè) 軟件工程 班 別 14級(jí)(2 )班 學(xué) 號(hào) 姓 名 馮杰俊 2015年11月25日專心-專注-專業(yè)一、課程題目 16. 為某公司編寫一個(gè)工資支付系統(tǒng)，用于計(jì)算某一類員工的月薪。該公司共有四類員工：領(lǐng)固定月薪的（SalariedEmployee），計(jì)時(shí)取酬的（HourlyEmployee，如果一月工時(shí)超過160小時(shí)，則還需對(duì)額外的工時(shí)支付加班費(fèi)）、按銷售額提成（CommissionEmployee）的和帶底薪并按銷售額提成的（BasePlusCommissionEmployee），其繼承層次結(jié)構(gòu)

2、如下所示。已知每類員工均有表示員工工號(hào)、姓名和出生年月的屬性，和用于計(jì)算員工月薪的方法。創(chuàng)建一個(gè)Employee變量數(shù)組，保存Employee類層次結(jié)構(gòu)中每個(gè)具體類對(duì)象的引用，對(duì)每個(gè)Employee顯示其工號(hào)、姓名、出生年月和月收入，如果當(dāng)月是Employee的生日所在的月份，則還另發(fā)給他100月作為紅包。二、題目分析與設(shè)計(jì) 1. 題目需求： 計(jì)算每一類員工的工資 創(chuàng)建一個(gè)Employee變量數(shù)組，保存Employee類層次結(jié)構(gòu)中每個(gè)具體類對(duì)象的引用 對(duì)每個(gè)Employee顯示其工號(hào)、姓名、出生年月和月收入2. 創(chuàng)造一個(gè)employee抽象類，其中有employee的基本屬性：工號(hào)、姓名、出生

3、年月和月收入，還有一個(gè)抽象方法，每一個(gè)類員工都是一個(gè)具體類，對(duì)抽象方法進(jìn)行不同的重載，以實(shí)現(xiàn)不同員工不同的工資計(jì)算方法，另外因?yàn)楸绢}沒有給出當(dāng)前月份、固定月薪、銷售每件產(chǎn)品的提成、時(shí)薪、加班費(fèi)等，因此本程序都以假設(shè)的方法自行設(shè)定，保存在多個(gè)接口中，在每個(gè)類中按需繼承3. 繼承層次結(jié)構(gòu)EmployeeSalariedEmployeeCommissionEmployeeHourlyEmployeeBasePlusCommissionEmployee4. 開發(fā)環(huán)境：Eclipse三、測試分析程序輸出：please enter employee type0:SalariedEmployee 1:Hou

4、rlyEmployee 2:CommissionEmployee 3:BasePlusCommissionEmployee用戶輸入：0（這里以固定月薪做示范，假定當(dāng)前為11月，固定月薪為5000）程序輸出：please enter details of this employee(name number birthyear birthmonth)for example:John9527199510用戶輸入：Jack5816199810name:Jacknumber:5816birthyear:1998birthmonth:10income:5000.please enter employee

5、type0:SalariedEmployee 1:HourlyEmployee 2:CommissionEmployee 3:BasePlusCommissionEmployee用戶輸入：0程序輸出：please enter details of this employee(name number birthyear birthmonth)for example:John9527199510用戶輸入：Jack5816199811（其他不變，月份輸入11）程序輸出：name:Jacknumber:5816birthyear:1998birthmonth:11income:5100.（發(fā)了100元
