How to split the array values and store in a string in android?
<p>I am getting the values from arraylist <strong>arr</strong> and storing those values in a string with comma separator. But for the last value also comma is adding. How can I remove that? Please help me...</p>

<p>My Code:</p>

<pre><code>ArrayList&lt;String&gt; arr;  
String str;

    for (int i = 0; i &lt; arr.size(); i++) {

                int kk = arr.size();
                System.out.println("splitting test" + arr.get(i));
                str += arr.get(i) + ",";

                System.out.println("result" + str);


            }
</code></pre>
