27866번: 문자와 문자열

 

방법1

import java.util.Scanner;

public class Main {
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);

        StringBuilder s = new StringBuilder(sc.nextLine());
        int i = sc.nextInt();

        System.out.println(s.charAt(i-1));
    }
}

 

방법2

한 줄에 문자열과 인덱스를 입력 받아, StringTokenizer를 사용함

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.StringTokenizer;

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        StringTokenizer str = new StringTokenizer(br.readLine());

        String s = str.nextToken();
        int i = Integer.parseInt(str.nextToken());
        System.out.println(s.charAt(i-1));
    }
}
