练习写一个工资结算系统

要求：公司将职员分为三类：部门经理、技术员和销售员。在发工资的时候，部门经理拿固定月薪8000元，技术人员按每小时100元领取月薪，销售人员按照500元底薪加当月销售额的4%进行提成，设计并实现一个工资结算系统。

思路：先创建一个所有员工共有属性和方法的员工类，在创建继承了员工类的经理、技术员和销售员子类，实现调用一种方法就能根据类得到不同结果。

代码如下：

package mt.wage;
/**
 * 员工类
 * @author mt
 *
 */
public abstract class Employee {
	protected String name;
	protected String pasition;
	
	
	public abstract int getSalary() ;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getDepartment() {
		return pasition;
	}

	public void setDepartment(String department) {
		this.pasition = department;
	}
	
	
}

package mt.wage;
/**
 * 经理类
 * @author mt
 *
 */
public class Manager extends Employee {
	public Manager(String name) {
		this .name = name;
		this.pasition = "经理";
	}
	@Override
	public int getSalary() {	
		return 8000;
	}
}

package mt.wage;
/**
 * 技术员类
 * @author mt
 *
 */
public class Programmer extends Employee {
	private int workTime;
	
	public Programmer(String name , int workTime) {
		this.name = name;
		this.workTime = workTime;
		this.pasition = "技术员";
	}
	
	public int getWorkTime() {
		return workTime;
	}
	public void setWorkTime(int workTime) {
		this.workTime = workTime;
	}

	@Override
	public int getSalary() {
		return 100 * workTime;
	}

}

package mt.wage;
/**
 * 销售员类
 * @author mt
 *
 */
public class Salesman extends Employee {
	private int sales;
	
	public Salesman(String name ,int sales) {
		this.name = name;
		this.sales = sales;
		this.pasition = "销售员";
	}
	@Override
	public int getSalary() {
		return 1200 + sales * 5/100;
	}

}

package mt.wage;

public class Test {
	public static void main(String[] args) {
		Employee[] em ={
				new Manager("张三"),
				new Programmer("李斯", 100),
				new Salesman("王五", 5000),
				new Programmer("赵钱", 50),
				new Salesman("孙犁", 10000),
				new Salesman("麻子", 8000)
				
		};
		for (Employee x :em) {
		System.out.println(x.pasition + x.name 
				+ "的"+ "工资为：" + x.getSalary());
		}
	}
}
