HJ4 字符串分隔

import java.util.Scanner;

// 注意类名必须为 Main, 不要有任何 package xxx 信息
public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        String str = in.nextLine();
        String[] data = str.split("");
        int len = data.length;
        int cycle = 0;
        while(len >= 8){
            int num = cycle * 8;
            String s = data[num + 0] + data[num + 1] + data[num + 2] + data[num + 3] + data[num + 4] + data[num + 5] + data[num + 6] + data[num + 7];
            System.out.println(s);
            len = len - 8;
            cycle++;
        }
        if(len != 0){
            String s = "";
            int num = cycle * 8;
            for(int i = 0; i < 8; i++){
                if(i < len){
                    s = s + data[num + i];
                } else{
                    s = s + "0";
                }
            }
            System.out.println(s);
        }
    }
}

1.读取字符串，并对字符串进行分割；

2.将字符数组每8个拼接成一个完整字符串；

3.判断剩余字符串大小，并用0补齐
