java根据输入的字符串和字节数来截取，输出对应字节数的字符串

public class Test {
    //要进行截取操作的字符串
    static String ss;
    //截取的字符串的字节数
    static int n;
    public static void main(String[] args) {
        System.out.println("请输入字符串：");
        //从键盘获取字符串
        Scanner scStr = new Scanner(System.in);
        //将Scanner对象中的内容以字符串的形式取出来
        ss = scStr.next();
        System.out.println("请输入字节数：");
        //从键盘获取字符串
        Scanner scByte = new Scanner(System.in);
        //将Scanner对象中的内容以数值的形式取出来
        n = scByte.nextInt();
        //方法与方法间的套用
        Interception(setValue());
    }
    //此方法的作用是将字符串转换成字符串数组
    public static String[] setValue(){
        //创建一个字符数组string
        String[] string = new String[ss.length()];
        for (int i = 0;i < string.length;i++){
            //将字符串ss中的第i个字符取出，放入字符数组中string中
            string[i] = ss.substring(i,i+1);
        }
        //将这个字符数组返回
        return string;
    }
    public static void Interception(String[] string){
        int count = 0;
        String m = "[\u4e00-\u9fa5]";
        System.out.println("每" + n + "字节进行划分的字符串如下所示：");
        for (int i = 0; i < string.length;i++){
            if (string[i].matches(m)){
                count = count + 2;
            }else {
                count = count + 1;
            }
            if (count < n){
                System.out.println(string[i]);
