package kr.co.softcampus.model;

import javax.servlet.http.HttpServletRequest;

public class Test2Service {

public static int minus(HttpServletRequest request) {

String str1=request.getParameter("data1");

String str2=request.getParameter("data2");

int number1=Integer.parseInt(str1);

int number2=Integer.parseInt(str2);

int result=number1-number2;

return result;

}

}

위 코드에서 진한 색 static이 왜 붙는지 궁금합니다.
