Java string splitting error


I need to split array of string and then save it into smaller string. Plz help me....what i am doing wrong..... 





for(int i=0; i<suburl.size(); i++){



       String temp = suburl.get(i);

   String[] data = temp.split(" ");



   Log.i("DATA 0", data[0]);

   Log.i("DATA 1", data[1]);

   Log.i("DATA 2", data[2]);

public static ArrayList<String> suburl = new ArrayList<String>();


where, 





suburl.get(0) = "alex 21 engineer"

   suburl.get(1) = "mike 22 lawyer"

   suburl.get(2) = "sunny 26 deisnger"

    What I think is that problably, not all your strings have two spaces. Just do not do things like data[x]. Use another loop to use those strings.

    This works for me, I am not sure what's wrong. You can cross check the input data again.

    List<String> suburl = new ArrayList<String>();
    suburl.add("alex 21 engineer");
    suburl.add("xyz 21 engineer");
    suburl.add("tim 21 engineer");
    suburl.add("gary 21 engineer");
    for(String temp : suburl) {
    String[] data = temp.split(" ");
    System.out.println("DATA 0 " + data[0]);
    System.out.println("DATA 1 " + data[1]);
    System.out.println("DATA 2 " + data[2]);
    }

    It is working fine for me:

    public class TestClass {

    public static void main(String args[]) {
    ArrayList<String> suburl = new ArrayList<String>();


    suburl.add("alex 21 engineer");
    suburl.add("xyz 21 engineer");
    suburl.add("tim 21 engineer");
    suburl.add("gary 21 engineer");

    for(int i=0; i<suburl.size(); i++){

    String temp = suburl.get(i);
    String[] data = temp.split(" ");

    System.out.println(data[0]);
    System.out.println(data[1]);
    System.out.println(data[2]);
    }


    Results:

    alex
    21
    engineer
    xyz
    21
    engineer
    tim
    21
    engineer
    gary
    21
    engineer

    Yuo must replace i<suburl.size(); to i<suburl.size() - 1;

    If you set your data in the ArrayList like this:

    suburl.get(0) = "alex 21 engineer"
    suburl.get(1) = "mike 22 lawyer"
    suburl.get(2) = "sunny 26 deisnger"
    suburl.get(3) = "kim 24 painter"


    I think you may want to change it and do suburl.add("alex 21 engineer");
