Java程序設計實驗報告學號 201405060432班級14信計姓名劉帆指導教師金玲玲實驗題目實驗七、類與對象31、 實驗目的1. 掌握抽象類的定義及抽象方法；2. 掌握抽象類的繼承特點；3. 掌握接口的定義和實現，體會接口的作用；2、 實驗內容1. 編寫雇員工資支付程序。定義抽象類雇員類Employee類，并提供方法computeSalary()。不同類型的雇員(定義子類)按不同的方式支付工資。 經理：每月獲得一份固定的工資； 銷售人員：在基本工資的基礎上加銷售提成； 一般工人：按工作天數計算工資； 試用類的繼承及相關機制描述上述功能需求并測試類。2. 程序功能：在程序中聲明一個自定義接口NL，用來計算一個人年齡。要求：定義接口NL，接口中定義屬性year，取值為2015；定義抽象方法求年齡age()和輸出信息output()；定義類A實現接口NL，A中定義屬性姓名和出生年份，其方法按需定義。3. 根據所提供接口的定義，續寫程序，要求體現對接口的多重繼承。(方法實現自定義)interface A int x=10; String fun1();interface B int y=5; void fun2();/續寫3、程序清單：（粘貼源程序代碼）1。abstract class Employee String name; public Employee(String name) =name; public String getName() return name;public abstract double computeSalary();class Manager extends Employee double Salary; public Manager(String name,double Salary) super(name); this.Salary=Salary;public double computeSalary() return Salary; class Salaesman extends Employee double baseSalary; int quantity; double univalent;public Salaesman(String name,double baseSalary,int quantity,double commision) super(name); this.baseSalary=baseSalary; this.quantity=quantity; this.univalent=univalent;public double computeSalary() return baseSalary+quantity*univalent;class Worker extends Employee int days; double daySalary;public Worker(String name,int days,double daySalary) super(name); this.days=days; this.daySalary=daySalary;public double computeSalary() return days*daySalary;public class EmployeeTest public static void main(String args) Manager m=new Manager(劉紅,5000); Salaesman s=new Salaesman(張三,2000,20,300); Worker w=new Worker(李梅,30,100); System.out.println(經理工資為：+puteSalary(); System.out.println(銷售工資為：+puteSalary(); System.out.println(工人工資為：+puteSalary(); interface A public static int x=10;public abstract String fun1();interface B public static int y=5;public abstract void fun2();public class Test implements A, B public String fun1() return +x;public void fun2() return +y;public static void main(String args) Test t=new Test();System.out.println(t.fun1();System.out.println(t.fun2();2。interface NL int year=2015; int age(); void output();public class A implements NL String name;int birthyear;public void setName(String name) = name;public void setBirthyear(int birthyear) this.birthyear = birthyear;public int age() return year-birthyear;public void output() return +age;3 interface A public static int x=10;public abstract String fun1();interface B public static int y=5;public abstract void fun2();public class Test implements A, B public String fun1() return 接口A的屬性值:+x;public void fun2() return 接口B的屬性值:+x;public static void main(String args) Test t=new Test()
