使用正则表达式将字符串拆分为多个字符串

Question

I was working on a task to parse a cucumber feature string where I need to split string into 5 like the following.

String data = "calls 'create' using 'POST' on some uri";

I was implementing the basic split functionality multiple times (without any regex which is very tedious) to generate the data into the following.

String dataArray[] = {"calls '","create","' using '","POST", "' on some uri"};

I wanted to obtain the names of dataArray[1] and dataArray[3] . Is there a way to generate the above dataArray using regex and split or some other straight forward method?

Answer 1

Here is a solution which use Regex:

public static void main (String[] args) {
  String data = "calls 'create' using 'POST' on some uri";
  String[] dataArray = new String[2];
  Matcher matcher = Pattern.compile("'[a-zA-Z]+'").matcher(data);
  int counter = 0;
  while (matcher.find()) {
    String result = matcher.group(0);
    dataArray[counter++] = result.substring(1, result.length() - 1);
  }
}

Output:

dataArray[0] --> create
dataArray[1] --> POST

Answer 2

Simply use this?

String dataArray[] = data.split("'");
->
[calls , create,  using , POST,  on some uri]
