Have tested with the input you have given, working perfectly in those cases

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;

}

Levenshtein distance suddently comes to mind: https://www.tutorialspoint.com/cplusplus-program-to-implement-levenshtein-distance-computing-algorithm

It calculates the necessary amount of insertion, deletion and exchanges to convert one string to another, you may easily change it to fit your own criteria for string difference.
