[Java] 문자열

✅ 공백은 문자열 아니라서 false 출력

package org.example;

public class Main {
    public static void main(String[] args) {
        System.out.println(isHanguel('안')); //true
        System.out.println(isHanguel('녕')); //true
        System.out.println(isHanguel('하')); //true
        System.out.println(isHanguel('세')); //true
        System.out.println(isHanguel('요')); //true
        System.out.println(isHanguel('.')); //false
        System.out.println(isHanguel(' ')); //false
    }

    static boolean isHanguel(char c) {
        return c >= '가' && c <= '힣';
    }
}
