题解 | #字符串分隔#

使用递归来给字符串截取和补足8位

import java.util.Scanner;

public class Main {

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

        while (scanner.hasNext()){
            String line = scanner.next();
            sub8(line);
        }
    }

    private static void sub8(String line){
        if (line.length() <= 8){
            int i = 8 - line.length();
            for (int j = 0; j < i; j++) {
                line = line.concat("0");
            }
            System.out.println(line);
        } else {
            String substring = line.substring(0, 8);
            System.out.println(substring);
            String substring1 = line.substring(8);
            sub8(substring1);
        }
    }
}
