Java string splitting error

Question

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]);
 }

here

 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"
   suburl.get(3) = "kim 24 painter"

and

   String[] data;

But what i am getting error when splitting is .......

  01-19 20:35:09.820: E/AndroidRuntime(1672): Caused by:    java.lang.ArrayIndexOutOfBoundsException
  01-19 20:35:09.820: E/AndroidRuntime(1672):   at  flash.com.MainActivity.onCreate(MainActivity.java:119)

  01-19 20:35:09.820: E/AndroidRuntime(1672):   at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1615)

at this point, Log.i("DATA 0", data[0]); Log.i("DATA 1", data[1]); — Programmer

It is working fine for me. Are you sure you are getting error at String[] data? — kosa

yes...if we have this data, its causing me the error, suburl.add("alex 21 engineer"); suburl.add("xyz 21 engineer"); suburl.add("tim 21 engineer"); suburl.add("gary 21 engineer"); — Programmer

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]);
}

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");

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;
