You can avoid creation of the intermediate ArrayList and compact the array
in place with something like this but
feel free to ignore if you like the original better:
{code}
int j = 0, len = topics.length;
for (int i = 0; i < len; ++i) {
if (null == topics[i] || 0 == topics[i].length()) continue;
if (i != j) topics[j] = topics[i];
++j;
}
this.topics = Arrays.copyOfRange(topics, 0, j);
{code}
