Java继承的简单实现


package inheritance;
//继承
public class ManagerTest {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Manager boss = new Manager("Carl Cracker",80000,1987,12,15);
		boss.setBonus(5000);
		
		Employee[] staff=new Employee[3];
		
		staff[0]=boss;
		staff[1]=new Employee("Harry Hacker",50000,1989,10,1);
		staff[2]=new Employee("tommy Tester",40000,1990,3,15);
		
		for(Employee e:staff){
			System.out.println("name="+e.getName()+",salary="+e.getSalary()+"  "+e.getHireDay());
		}
	}

}

员工类

package inheritance;
import java.time.*;
public class Employee {
	private String name;
	private double salary;
	private LocalDate hireDay;
	
	public Employee(String name,double salary,int year,int month,int day){
		this.name=name;
		this.salary=salary;
		hireDay=LocalDate.of(year, month,day);
	}
	
	public String getName(){
		return name;
	}
	
	public double getSalary(){
		return salary;
	}
	public LocalDate getHireDay(){
		return hireDay;
	}
	
	public void raiseSalary(double byPercent){
		double raise =salary*byPercent/100;
		salary +=raise;
	}
}

经理类继承员工类并添加特有属性

package inheritance;

public class Manager extends Employee {
		private double bonus;
		
		public Manager(String name,double salary,int year,int month,int day){
			super(name,salary,year,month,day);
			bonus=0;
		}
		
		public double getSalary(){
			double baseSalary=super.getSalary();
			return baseSalary+bonus;
		}
		
		public void setBonus(double b){
			bonus=b;
		}
}
