Servlet 기본 출력

response.setContentType("text/html; charset=utf-8");

==>

response.응답을 할건데

setContentType이런 타입으로 보내줄거야

("text/html")text타입이고 html형식으로 보내줄거야

charset=utf-8해석방식으로 해석해야해

PrintWriter out = response.getWirter();

==>

PrintWriter 객체가 리턴됨

아웃이라는 통로가 마련된 것임

out.print("<h1> 1-10까지 출력 ! <h1>");

==>

ln 안 써도 됨, 어차피 html이라 br태그 써야 개행(엔터, 한 줄 밑으로 내리는 것)됨

for(int i=1; i<=10; i++){

out.print(i + "<br>"); 

}

out.close();

==>

객체 닫아주기
