Java按长度拆分String字符串

不废话，直接上代码.

/**
     * 把String按一定长度拆分，返回ListString
     *
     * @param str
     * @param len
     * @return
     */

    public List<String> getListStr(String str, int len) {
        List<String> listStr = new ArrayList<>();
        int strLen = str.length();
        int start = 0;
        int num = len;
        String temp = null;
        while (true) {
            try {
                if (num >= strLen) {
                    temp = str.substring(start, strLen);
                } else {
                    temp = str.substring(start, num);
                }
            } catch (Exception e) {
                LogUtils.i("拆分完毕", "");
                break;
            }
            listStr.add(temp);
            start = num;
            num = num + len;
        }
        return listStr;
    }
