增加左边填充字符串

Question

我有String = 82868184847，我想用000到999之间的数字来填充它。我试过这样做：

 for (int i = 0; i < 1000; i++) {

        number = String.format("%02d", i);
        paddedNum = number;
   }

我希望我的输出为
      00082868184847
      00182868184847
      00282868184847
      ...
      99982868184847

但我得到了      00082868184847
01082868184847
02082868184847
....

String key = "82868184847";String salt ; for (int i = 0; i <= 999; i++) { salt = String.format("%03d", i); System.out.println( salt + key);}
