check string with delimiter expected

Question

I want to split string got from bluetooth. i'm using

StringTokenizer  splitStr = new StringTokenizer(readMessage, "\\|");
String numberSpeed = splitStr.nextToken();  //splitStr[0].replaceAll("\\D+","");
String numberTorque = splitStr.nextToken();  //splitStr[1].replaceAll("\\D+","");
numberSpeed = numberSpeed.replaceAll("\\D+","");
numberTorque = numberTorque.replaceAll("\\D+","");

Did it with split string before. If i get corupted data without delimiter the app crashes while trying to do impossible.

• How to check if there is delimiter or not and then proceed split or skip it?

Answer 1

you can check for delimeter in string by contains() method

if(str.contains("_your_delimiter")) {   //for safe side convert your delimeter and search string to lower case using method toLowerCase()
     //do your work here
}
