[Java]백준 2588번: 입출력과 사칙연산 단계 - 곱셈

1. BufferedReader 사용

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;
 
public class Main {
	public static void main(String[] args) throws IOException {
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		int A = Integer.parseInt(br.readLine());
		String B = br.readLine();
		char[] b = B.toCharArray(); //toCharArray() : 문자열을 char 배열 형태로 반환해주는 메소드
			
		System.out.println(A * (b[2]-'0'));
		System.out.println(A * (b[1]-'0'));
		System.out.println(A * (b[0]-'0'));
		System.out.println(A * Integer.parseInt(B));
