Replicating String.split with StringTokenizer

Question

Encouraged by this, and the fact I have billions of string to parse, I tried to modify my code to accept StringTokenizer instead of String[]

The only t

You could do something like that. It's not perfect, but it might be working for you.

public static List find(String test, char c) {
    List list = new Vector();
    start;
    int i=0;
    while (i<=test.length()) {
        int start = i;
        while (i

If possible you can ommit the List thing and directly do something to the substring:

public static void split(String test, char c) {
    int i=0;
    while (i<=test.length()) {
        int start = i;
        while (i

On my System the last method is faster than the StringTokenizer-solution, but you might want to test how it works for you. (Of course you could make this method a little shorter by ommiting the {} of the second while look and of course you could use a for-loop instead of the outer while-loop and including the last i++ into that, but I didn't do that here because I consider that bad style.
