First you should use a StringBuilder for concatenation of your Strings.

take a look here:

StringBuilder sb = new StringBuidler();
Node tempNode = actualElement;

while (tempNode.next() != actualElement)
{
    if (sb.length() == 0)
    {
        sb.append("[").append(tempNode.data().toString());
    }
    else
    {
        sb.append(", ").append(tempNode.data().toString());
    }
    tempNode = tempNode.next();
}
sb.append(", ").append(tempNode.data().toString()).append("]");
return sb.toString();
