java算工资的编程题？

class Salary{

private int no;

private String name;

private double deal;

private double tax;

public Salary(int no,String name,double deal,double tax){

this.no=no;

this.name=name;

this.deal=deal;

this.tax=tax;

}

public double count(){

return this.deal-this.tax;

}

public void output(){

System.out.println("工号"+this.no);

System.out.println("姓名"+this.name);

System.out.println("应发工资"+this.deal);

System.out.println("税金"+this.tax);

System.out.println("实发工资"+count());

}

public static void main(String[] args){

Salary a=new Salary(1,"张三",1000,200);

a.output();

Salary b=new Salary(2,"李四",1500,200);

b.output();

}

}

怎样计算工资包括年工资,周工资,月工资，用java编写程序
