해결법

방법 1

import java.util.Scanner;

public class Solution {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String a = sc.next();
        String[] str = a.split("");
        
        for (int i = 0; i < str.length; i++){
            System.out.println(str[i]);
        }
    }
}

• println()

방법 2

import java.util.Scanner;

public class Solution {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String a = sc.next();
        
        for (char ch : a.toCharArray())
            System.out.println(ch);
    }
}

• toCharArray() : 문자열을 문자배열로 변환

  참고: String 클래스

방법 3

import java.util.Scanner;

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

        for (int i = 0; i < a.length(); i++) {
        	System.out.println(a.charAt(i));
        }
    }
}
