StringTokenizer get the third element

Question

I am very new to android..Can you please help me to solve this. I have a string like

DOCOMOBH-TATA DOCOMO Mobile Bihar-SRSBL53-DOCOMOBH

and I have to get the third element. i.e SRSBL53

I have done this.

StringTokenizer stringTokenizer = new StringTokenizer(billerlist, "-");
String strBillerId = stringTokenizer.nextToken();

Thus i have got the first element DOCOMOBH.but how to get the third one.Thanks.

Answer 1

you can use split(regex) on your String

String billerlist = "DOCOMOBH-TATA DOCOMO Mobile Bihar-SRSBL53-DOCOMOBH";

String[] array = billerlist.split("-");
if(array.length>2){
    String thirdElement = array[2];
}    

Answer 2

Try using TextUtils.StringSplitter, a StringTokenizer would have to read at least n tokens in order to determine which is the n-th one. Thus it might be easier to just create a string array using StringSplitter

TextUtils.StringSplitter splitter = new TextUtils.SimpleStringSplitter("-");

splitter.setString(billerList);
if(splitter.size>2){
    String myString = splitter[2];
}

Answer 3

Optimized answer is provided by others but for the sake of answering what you are trying see the following code

    String billerlist = "DOCOMOBH-TATA DOCOMO Mobile Bihar-SRSBL53-DOCOMOBH";
    StringTokenizer stringTokenizer = new StringTokenizer(billerlist, "-");
    String requiredData = null; //local variables must be initialized before using
     int count = 1;
    while(stringTokenizer.hasMoreTokens()) {
        String data = stringTokenizer.nextToken();
        if(count == 3) {
            requiredData = data;
        }
        count++;
    }
    if(requiredData != null) {
        System.out.println("Required data is " + requiredData);
    }
    else {
        System.out.println("Required data not present");
    }

and the output is

Required data is SRSBL53
