Question

How can I read an email address as a token?

I saw that the tokenizer method has a limit of 16 bits of length, well my token is like this:

command [e-mail] 50

I want to be able to store the email (can be any email address) and the number (can vary from 5-1500). I dont care about the command token.

My code looks like this:

String test2 = command.substring(7);
StringTokenizer st = new StringTokenizer(test2);
String email = st.nextToken();
String amount = st.nextToken();

So if you have your data in a variable called command you could simply do:

StringTokenizer st = new StringTokenizer(command);
st.nextToken(); //discard the "command" token since you don't care about it
String email = st.nextToken();
String amount = st.nextToken();

Alternatively, you can use “split” on the string to load it into an array:

String[] tokens = command.split("\w"); //this splits on any whitespace, not just the space
String email = tokens[1];
String amount = tokens[2];
