An alternative (and preferable) way to clear the vector is to use {{vector.clear()}}. Likewise, if a range of elements has to be released from a vector, {{vector.subList(fromIndex, toIndex).clear()}} can be used. In this case the {{fromIndex}} and the {{toIndex}} would both be {{0}} as the {{count}} variable is {{1}} on each iteration. \[[API 06|AA. Java References#API 06]\] |
