hi v2_vehooi

check out the following code, is that your requirement?
[HTML] class RandomGen
{
public static void main(String args[])
{
int i=(int)(100+((int)Math.round(100*Math.random())));
System.out.println(i);
}
}
[/HTML]

I would suggest adding one to the end of the generated number or else you wont ever reach 200.

hi v2_vehooi

check out the following code, is that your requirement? [HTML] class RandomGen { public static void main(String args[]) { int i=(int)(100+((int)Math.round(100*Math.random()))); System.out.println(i); } } [/HTML] regards srinivas

thank you very much
this is what i need for the output
but can u explain to me more detail about this code how it run?
like the Math.round, why u need use this? and how u make the range between 100 to 200? if between this range i need to include the 200 so how

The best way is to add one to the end. You don't need the round method; A better choice would be the Math.ceil() method since it rounds up.

int i=(int)(101+((int)100*Math.random()));

or

int i=(int)(100+((int)101*Math.random()));

or

int i=(int)(100+((int)100*Math.random()))+1; //My choice
