random number generation

How to generate random number in java?

Math.random()

Will generate a random number between 0 and 1.

:)

Or you can instantiate an object of Random
import java.util.Random;

Random x = new Random();
x.nextInt(5); returns an int value [0,5)

but it gives error

impot java.util.Ramdom

class a
{
public static void main()
{
Random i=new Random();
}

}

impot???
Ramdom???

I'm guessing you just typed that in the thread, so post the error you get. If you didn't, check your spelling :)

Also thought you needed String[] args as input in the main procedure.
