Randomly generate a number

Recommended Posts

I need to automatically generate a ticket_id number, so I did just that in a jsp file.


Then I want to display that randomly generate ticket number in the Ticket ID text field on my html page.


Then I am going to get that ticket number from the text field and insert it into my database through the jsp again.


Am I complicating things? Why doesn't the below code work?


Should I just execute the random ticket number when the user clicks the submit button on the html form and show a box with the ticket number?


Please help and thank you if you do. Any advice is very helpful.

Random rand = new Random();int randomnumber = rand.nextInt(90000) + 10000;Ticket ID:<input type="text" name="ticketid" value="<%randomnumber%>"></input><br/>

Okay, why should i read that? That didn't help me. I need hep generating a number. I already know about syntax and all that...Just because I post here doesn't mean I didn't research anything. I've been looking and trying things.

Well, did you read it carefully?

<%Random rand = new Random();int randomnumber = rand.nextInt(90000) + 10000;%>Ticket ID:<input type="text" name="ticketid" value="<%=randomnumber%>"/><br/>
