【开发笔记】- 输出String字符串使其文本对齐

 

需求

  • 一段文本做每64个字节换行处理,并添加对应的头尾注释

代码实现

public static String certFormat(String code, String beginTitle, String endTitle){
  StringBuffer sb = new StringBuffer(cert);
  for (int i = 0; i < cert.length(); i++) {
    char c = cert.charAt(i);
    if(i%64 ==0 && i != 0){
      sb.insert(i,"\n\t");
    }
  }
  sb.insert(0, beginTitle+"\n\t");
  sb.insert(sb.length(), "\n\t"+endTitle);
  return sb.toString();
}

输出文本
