Answer 1

已使用您提供的輸入進行測試，在這些情況下完美運行

private static String getDifferentChar(String data, String compareWithData) {

    if(data == null || compareWithData == null) return null;
    int dataLength = data.length();
    int compareWithDataLength = compareWithData.length();

    String differentChar = "";
    int pos =0;

    if(pos<dataLength && compareWithDataLength >=dataLength) {
       while(pos<dataLength) {
      if(data.charAt(pos) != compareWithData.charAt(pos)) {
        differentChar+= "" + compareWithData.charAt(pos);
        }
             pos++;
       }

        if(compareWithDataLength > dataLength) {
             differentChar+= "" + compareWithData.substring(dataLength);
        }

    } 
    return differentChar;

}

突然想到Levenshtein距離： https : //www.tutorialspoint.com/cplusplus-program-to-implement-levenshtein-distance-computing-algorithm

它計算將一個字符串轉換為另一個字符串所需的插入、刪除和交換量，您可以輕松更改它以適合您自己的字符串差異標准。
