안경잡이개발자님 블로그 > 사원 연봉 계산기 문제

 

사실 학원 다니면서 한 번 풀었었지만 푼 거에만 의의를 두고 코드를 어디에 업로드 안 해놨길래 다시 풀어봤다.

아직 많이 부족하다는 거 한번 더 느꼈고 이 코드가 마음에 안 드는데 일단은 이게 내 한계다. 

 

Employee.java

package salaryCal;

public class Employee {

	String name;
	double salary; 
	double annual_salary;
	

	public String toString() {
		return "<<<Employee>>> \n "
				+ "Name : " + name + "\n"
				+ "M_salary : " + salary + "\n"
				+ "AnnualSalary : " + salary * 12 + "\n";
	}
	
	public String getName() {
		return name;
	}

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

	public double getSalary() {
		return salary;
	}

	public void setSalary(double salary) {
		this.salary = salary;
	}

	public double getAnnual_salary() {
		return annual_salary;
	}

	public void setAnnual_salary(double salary) {
		this.annual_salary = salary * 12;
	}
}

Salesman.java

package salaryCal;

public class Salesman extends Employee {

	double annual_sales;
	
	public double annualSalary() {
		if(annual_sales * 0.02 > 20000) {
		annual_salary = (salary * 12) + 20000;
		} else {
			annual_salary = (salary * 12) + (annual_sales * 0.02);  
		}
		
		return annual_salary;
	}
	
	public String toString() {
		return "<<<Salesman>>> \n "
				+ "Name : " + name + "\n"
				+ "M_salary : " + salary + "\n"
				+ "AnnualSales : " + annual_sales + "\n"
				+ "AnnualSalary : " + annual_salary + "\n";
	}

	public double getAnnual_sales() {
		return annual_sales;
	}

	public void setAnnual_sales(double annual_sales) {
		this.annual_sales = annual_sales;
	}

	public double getAnnual_salary() {
		return annual_salary;
	}

	public void setAnnual_salary(double annual_salary) {
		this.annual_salary = annual_salary;
	}
}

Executive.java

package salaryCal;

public class Executive extends Employee {
	
	double stock_price;
	double bonus = 0;
	
	public double annualSalary() {
		
		if(stock_price >= 50) {
			bonus = 30000;
		}else {
			bonus = stock_price; 
		}
		
		annual_salary = salary * 12 + bonus;
		
		return annual_salary;
	}
	
	public String toString() {
		return "<<<Executive>>> \n "
				+ "Name : " + name + "\n"
				+ "M_salary : " + salary + "\n"
				+ "Stock_Price : " + stock_price + "\n"
				+ "AnnualSalary : " + annual_salary + "\n";
	}


	public double getStock_price() {
		return stock_price;
	}

	public void setStock_price(double stock_price) {
		this.stock_price = stock_price;
	}

	public double getAnnual_salary() {
		return annual_salary;
	}

	public void setAnnual_salary(double annual_salary) {
		this.annual_salary = annual_salary;
	}	
}

중복되는 코드들 참 마음에 안든다.
