csv file after loadString(), split() and append(), same value of String data won't be equal any more

Hi Everyone, I tried to load csv file into processing, I used loadString(), split(), and StringList append method to get the string data out of the file, however, in the end the same value string won't be equal any more. I tried to do it with String Array, and it gave me the same outcome.

However, if I use handmade String data, there is no such problem.

The problem occurs with the code below. The part of the data is also attached. Thanks!

    String mystock = "wfgk1min.csv";
    String[] rawData;
    StringList dates = new StringList();
    IntList minutes = new IntList();
    FloatList prices = new FloatList();
    FloatList volumes = new FloatList();
    void setup() {

      loadData(mystock);

      println(dates.get(0));
      println(dates.get(1));
      println(dates.get(0) == dates.get(1));
      printArray(dates);
    }

    void loadData(String filename) {

      rawData = loadStrings(filename);
      for (int i = 0; i < rawData.length-1; i++) {

        String[] thisRow = split(rawData[i], ","); 
        //printArray(thisRow);
        dates.append(thisRow[0]);
        minutes.append(int(thisRow[1]));
        prices.append(float(thisRow[5]));
        volumes.append(float(thisRow[6])*0.0001);
      }
    }

data is like the following:

2015/01/30,931,30.9,30.9,30.7,30.74,74300,2292514
2015/01/30,932,30.74,30.75,30.71,30.71,48400,1487314
