숙제- 월급구하기(method, BufferedReader)

월급 계산 프로그램 이름, 직급, 기본급, 수당을 입력하여 세금과 월급을 계산하시오 세율은 급여가 4,000,000 만원 이상이면 3% 아니면 2%로 한다 만약 이 문제를 다 풀었다면 세금은 calcTax() 월급은 calcSalary()를 이용해서 계산하시오 급여 = 기본급 + 수당 세금 = 급여 * 세율 월급 = 급여 - 세금 [실행결과] 이름 입력 : 홍길동 직급 입력 : 부장 기본급 입력 : 4500000 수당 입력 : 200000    *** 홍길동 월급 명세서 *** 직급 : 부장 기본급      수당      급여   세율   세금   월급 4500000      200000     4700000   3%   xxxxx   xxxxxxx
