problems printing an arraylist

// FOLLOWING GIVES ME A NULL POINTER EXCEPTION --- ANY HELP
// GREATLY APPRECIATED

import java.util.ArrayList;
public class Example
{
public static ArrayList<Integer> nums;
public static void numQuest()
{
int k = 0;
Integer zero = new Integer(0);

nums.add(0);
nums.add(0);
nums.add(4);
nums.add(2);
nums.add(5);
nums.add(0);
nums.add(3);
nums.add(0);
while ( k < nums.size())
{
if (nums.get(k).equals(zero))
nums.remove(k);
k++;
}
System.out.print("contents of nums: " + nums );
System.out.print("\n");
}



public static void main (String[] args)
{

numQuest();

You need to initialize your arraylist.

Code:

---

public static ArrayList<Integer> nums = new ArrayList<Integer>();
