주의할 점: 자바에서는 몇몇 문자는 단독으로 써서 출력할 수 없다. (대표적으로 백슬래시와 큰 따옴표)그래서 문자를 출력하기 위해 " 백슬래시(\) + 문자" 조합을 만드는 것을 'Escape Sequance' 라고 한다.  import java.io.BufferedWriter;import java.io.IOException;import java.io.OutputStreamWriter;public class Main { public static void main(String[] args) throws IOException { BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out)); bw.write..
