StringTokenizer

StringTokenizer

Question:
After:

StringTokenizer st = new StringTokenizer(line);

Do I have to write:

String key = new String(st.nextToken());

or is it enough to write:

String key = st.nextToken();

Answer:
It is sufficient to write

String key = st.nextToken();

The nextToken() method will allocate a newString containing the next token and returnit. Creating a copy of that String isredundant and wastes memory and cycles.
