How do i count the number of elements in an array?

I am splitting the string using StringTokenizer. I also want to find the top and the bottom element of an array.

String mCust = request.getQueryString("cust");
StringTokenizer st = new StringTokenizer(mCust, ",");
String[] tokens = new String[st.countTokens()];
int i = 0;
while(st.hasMoreElements())
tokens[i++] = (String)st.nextElement();

PLEASE DO NOT AWARD PTS TO ME SINCE A SOLUTION HAS ALREADY BEEN GIVEN. I AM ONLY GIVING AN ALTERNATIVE. Pts should goto allahabad.

that is a good way to get all and show the top and bottom.

but if you just want the top and bottom just store the first and last in two string vars rather than using an array

String mCust = Request.QueryString("cust");
StringTokenizer st = new StringTokenizer(mCust, ",");
int totTokens = st.countTokens();
String firstToken = null;
String lastToken = null;
int i = 0;
while(st.hasMoreElements()) {
if (i == 0) {
firstToken = st.nextToken();
}
else if (i == (totTokens-1)) {
lastToken = st.nextToken();
}
else {
String dummyString = st.nextToken();
dummyString = null;
}
i++;
}
System.out.println("Top token : " + firstToken);
System.out.println("Bottom token : " + lastToken);
