public boolean remove(Object o) {
final Object[] es = elementData;
final int size = this.size;
int i = 0;
found: {//这是什么
if (o == null) {
for (; i < size; i++)
if (es[i] == null)
break found;
} else {
for (; i < size; i++)
if (o.equals(es[i]))
break found;

return false;
}
fastRemove(es, i);
return true;
}
arraylist的remove方法,注释处的found是什么?
