String[] colors = new String[]{ cArrayList.size() }; What are you attempting to do here? Create an array of Strings of that size or put the size of that arraylist as the first element in the colors array? – Marc Baumbach Sep 19 '15 at 5:06

As per your requirement you can do following if your cArrayList is ArrayList

String[] colors = new String[cArrayList.size()] ;
for(int i=0;i<cArrayList.size();i++)
{
  colors[i]=cArrayList.get(i);
}

Alternatively, you can use the more concise and faster approach:

String[] colors = cArrayList.toArray(new String[cArrayList.size()]);

Like in Core Java you convert int[] to List<Integer> same as the code shows below: 

    int[] ints = {100,1000,10000};
    List<Integer> ls = new ArrayList<Integer>();
    for (int index = 0; index < ints.length; index++)
    {
        ls.add(ints[index]);
    }

To convert your integer value to a string use:

String.valueOf(insert your integer value here);
