自己电脑上做网站,ueditor上传wordpress,wordpress为什么安装不了,泰国网站的域名实例需求#xff1a;实现一个名为Person的类和它的子类Employee#xff0c;Manager是Employee的子类#xff0c;设计一 个类Add()用于涨工资#xff0c;普通员工一次能涨10%#xff0c;经理能涨20%。具体要求如下:(1)Person类中的属性有#xff1a;姓名name String(类型)…实例需求实现一个名为Person的类和它的子类EmployeeManager是Employee的子类设计一 个类Add()用于涨工资普通员工一次能涨10%经理能涨20%。具体要求如下:(1)Person类中的属性有姓名name String(类型)地址address(String类型)定义该类的构造方法(2)Employee 类中的属性有工号ID(String类型)工资wage(double类型)工龄(int 型)定义该类的构造方法(3)Manager类中的属性有级别level(String类型)定义该类的构造方法(4)编写一个测试类产生一个员工和一个经理给该员工和经理涨工资。1、利用继承的特性当子类没有相应的成员方法时调用父类的同名方法。Person.javapackage person_employee;public class Person {private String name ;private String address ;//定义构造方法public Person(String name, String address){this.name name;this.address address;}}Employee.javapackage person_employee;// 继承Person类public class Employee extends Person {private String ID ;private double wage 0;private int age 0;public Employee(String name, String address, String ID, double wage, int age){super(name, address); //调用父类的构造方法this.ID ID;this.wage wage;this.age age;}public double add(String position){// 判断职位if(position 0){wage wage*1.2;}else{wage wage*1.1;}return wage;}//设置get/set方法public double getWage() {return wage;}public void setWage(double wage) {this.wage wage;}}Manager.javapackage person_employee;//继承Employee类public class Manager extends Employee{private String level ; //1为普通员工0为经理public Manager(String name, String address, String ID, double wage, int age, String level){super(name, address, ID, wage, age);this.level level;}//设置get/set方法public String getLevel() {return level;}public void setLevel(String level) {this.level level;}}Test.javapackage person_employee;public class Test {public static void main(String[] args) {// 新建对象Manager normal new Manager(wsl, jit, 12, 1000, 2, 1);Manager manager new Manager(ctl, jitt, 123, 10000, 10, 0);// 传入职位Manager类型的对象没有add()方法所以自动搜寻其父类调用add()方法normal.add(normal.getLevel());manager.add(manager.getLevel());System.out.println(normal wage is:normal.getWage());System.out.println(manager wage is:manager.getWage());}}打印结果打印结果2、定义抽象类定义抽象类在子类中实现不同的抽象方法。Person.javapackage person_employee;public class Person {private String name ;private String address ;//定义构造方法public Person(String name, String address){this.name name;this.address address;}}Employee.javapackage person_employee;public abstract class Employee extends Person {private String ID ;private double wage 0;private int age 0;public Employee(String name, String address, String ID, double wage, int age){super(name, address);this.ID ID;this.wage wage;this.age age;}//定义抽象方法public abstract void add(String position);//设置get/set方法public double getWage() {return wage;}public void setWage(double wage) {this.wage wage;}}Manager.javapackage person_employee;public class Manager extends Employee{private String level ;public Manager(String name, String address, String ID, double wage, int age, String level){super(name, address, ID, wage, age);this.level level;}//实现抽象方法public void add(String position){double wage super.getWage();if(position 0){super.setWage(wage*1.2);}else{super.setWage(wage*1.1);;}}public String getLevel() {return level;}public void setLevel(String level) {this.level level;}}Test.javapackage person_employee;public class Test {public static void main(String[] args) {Manager normal new Manager(wsl, jit, 12, 1000, 2, 1);Manager manager new Manager(ctl, jitt, 123, 10000, 10, 0);normal.add(normal.getLevel());manager.add(manager.getLevel());System.out.println(normal wage is:normal.getWage());System.out.println(manager wage is:manager.getWage());}}打印结果一样。3、在2的基础上利用多态实现方法的重载Manager.javapackage person_employee;public class Manager extends Employee{private String level ;public Manager(String name, String address, String ID, double wage, int age, String level){super(name, address, ID, wage, age);this.level level;}//实现抽象方法public void add(){double wage super.getWage();super.setWage(wage*1.1);}public void add(String position){double wage super.getWage();super.setWage(wage*1.2);}public String getLevel() {return level;}public void setLevel(String level) {this.level level;}}Test.javapackage person_employee;public class Test {public static void main(String[] args) {Manager normal new Manager(wsl, jit, 12, 1000, 2, 1);Manager manager new Manager(ctl, jitt, 123, 10000, 10, 0);normal.add();manager.add(manager.getLevel());System.out.println(normal wage is:normal.getWage());System.out.println(manager wage is:manager.getWage());}}打印结果一样
