Integer中提供字符串按照二进制转化为十进制的方法

import java.util.ArrayList;
import java.util.Scanner;

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

        int count = 0;
        ArrayList<Integer> result = new ArrayList<>();
        lable:
        while(true){
            for (int i = 1; i < 11; i++) {
                if(i > sb.length()){
                    break lable;
                }
                count++;
                int num = Integer.parseInt(sb.substring(0,i),2);
                result.add(num);
                sb.delete(0,i);
            }
        }
        System.out.println(count);
        for (Integer res : result) {
            System.out.print(res+" ");
        }
    }
    
}
