OutOfMemoryError: Java heap space on ArrayList

I want to transfer value of even indexed array(pos) to an arraylist(words), everytime pos has two or more value i get OutOfMemoryError. Is something wrong? Because I get OutOfMemoryError: Java heap space

    ArrayList<String> token = new ArrayList<String>();
    ArrayList<String> words = new ArrayList<String>();
    for (String a : token)
    {
        temp = temp + " " + a;
        pos = a.split("[_\\s]+");

    }
      int c=0;
      for(int i=0; i<=pos.length; i+=2) {
            words.add(pos[i]);
            c++;
    }

In your second for loop you don't increment i by 2, you set i to 2, resulting in an infinite loop.

use i+=2 instead of i=+2

There is another problem with that for loop: it can occur that i == pos.length. In that case pos[i] will cause an ArrayIndexOutOfBoundsException.
