In this tutorial we are going to make a use of random() method of the Math class. We are using the number between 10 to 100. It will display you the new automatically generated number. Each time you will refresh the page the new random number will be generated.
The code of the program is given below:
<html> <HEAD> <TITLE>Random in jsp</TITLE> </HEAD> <BODY> <H3 ALIGN="CENTER"> Ramdom number from 10 to 100 : <FONT COLOR="RED"> <%= (int) (Math.random() * 100) %> </FONT> </H3> <H4 ALIGN="">Refresh the page to see the next number.</H4> </BODY> </HTML>
