Currently you are trying to return the full array. What you're needing to do is return the size of the array, which in Java can be done with the Array.length parameter. For example, if you want to find the length of an array called mArray you would do
size = mArray.length;
Please let us know if this answers your question or if you need more assistance. Also, if you need more assistance, could you post your updated code so we can help you from where you are at.
