String[] myArray = result.split(",");

This returns an array separated by your argument value, which can be a regular expression.

String result=",17,18,19,";
String[] resultArray = result.split(",");
System.out.printf("Elements in the array are: ");
    for(String resultArr:resultArray)
    {
        System.out.println(resultArr);
    }

Try split()

Assuming this as a fixed format,

String result=",17,18,19,";
String[] resultarray= result.substring(1,result.length()).split(",");
for (String string : resultarray) {
    System.out.println(string);
}

//output : 17 18 19

That split() method returns

the array of strings computed by splitting this string around matches of the given regular expression

First remove leading commas:

result = result.replaceFirst("^,", "");

If you don't do the above step, then you will end up with leading empty elements of your array. Lastly split the String by commas (note, this will not result in any trailing empty elements):

String[] arr = result.split(",");

One liner:

String[] arr = result.replaceFirst("^,", "").split(",");

You can do like this :

String result ="1,2,3,4";
String[] nums = result.spilt(","); // num[0]=1 , num[1] = 2 and so on..
